Absolutely agree. Multiple versions, clients, servers, sync is just broken, has been for at least 18 months.
Right now, in spite of version upgrade on server, client, reboots, etc, all clients are stuck in “Waiting to download”
#1 thing I wish they’d fix.
Wow I can’t believe that actually fixed it for me on the Android app. My syncs had been stuck on “50%” for the longest time. But no actual errors were showing up on the Syncing screen.
The fix was to manually go into the Plex app settings and add “Storage” to the allowed permissions. Seems the reason it wouldn’t download was because Plex had no permissions to write to storage, but also never asked me to give it permission, like apps normally do. So that was the bug for me.
I’m on a Pixel 2XL and Android 10.
That actual fixed the issue on LG V30 as well … WoW. Why is permission request then not being requested when the app is installed?
Nevermind… It may have been another bug, saying it started to download, but the file is not actually on my device after it said it downloaded it. I tried deleting and re-downloading the file now that Storage permission is granted. It’s still saying “50% - Downloading” on my device, and “Waiting to be downloaded” on the server. What the ----.
I tried several of the fixes in this forum, but the only things that worked for me on these two Android devices (Fire HD8 Kids and Pixel 3) were:
After those 3 steps, I was able to download again. I had no issues with my iOS Plex App (iPhone 8).
thx - will give it a try.
Just wanted to add another user having this problem. Every time I want to use this feature, I have to uninstall and re-install the app.
Slow glad I bought lifetime /s
Whether it’s my Pixel 4 or my Amazon Fire tablet, this happens. This feature is so broken.
Both nice and sad to see that I’m not the only one having this issue.
And most sadly when the devs obviously don’t take this seriously or even cares it seems…
macOS (server) -> iPad Pro
I have the same issue since the last server update. Tried storage permission, reinstall but nothing helps 
Did try every here provided fix, but nothing helped. Even not to install the Smartphone completely new. And there is still the Problem with dynamic Playlists, which are playing the wrong Songs when the Phone is offline.
… no, it’s not about SQLite. You are telling crap. Sorry Man.
Is there any way to manually correct this without doing a full reinstall or deleting my sync’d data? Like, clearing that index or something?
Same here, after last Plex server update, both Android devices stopped syncing, hanging at the 50% mark.

So it looks like the client is hitting an invalid path. This is on the same network as the Plex Server. And with 2 instances of Plex running, one on FreeNAS and the other on an Ubuntu VM.
Plex Support, let me know if you want me to DM you the logs.
G.
The problem (waiting to download - stuck at 50%) only occurs when I try to sync TRANSCODED content. Playing transcoded content in “real time” (without syncing) works absolutely fine.
If I sync NON transcoded content (quality: original) then it is downloaded 100%. Anybody experience the same?
Server is on nvidia shield, clients are android mobile and tablet.
Any feedback is welcome - thanks!
Same for me…
Server Version 1.18.4.2171
I have 3 TV shows which I am trying to sync to my ipad. They have all converted but are now stuck in “Waiting to be downloaded”.
I have an active internet connection.
What is the app waiting for?
Sorry for my english.
I have problem with sync (stuck on waiting to download) from my Nvidia Shield TV server (any content - transcoded or original) after last update to Plex Media Server 1.18.4.2171. OK, I try different ways - delete plex from tablet (mi pad 4), clean PMS cash on shield TV - no result. Then I downoloaded Plex Media Server 1.18.3.2156 and try to install it on shield - error. Then I can’t find any way besides to delete Updates of PMS on Nvidia Shield TV and install this APK - problem was solved! Now sync work perfect, but I lost my configuration and should make it from beginning.
So, I can suppose, that Server Version 1.18.4.2171 have problem with sync and only way is wait for new update (or will install old version of PMS with lost config).
Based on the feedback from users in this thread, it seems like the problem (stuck waiting on download at 50% for transcoded content), is because the latest version of Plex Media Server (1.18.4.2171) simply does not support it.
Could a representative from Plex please confirm this? People are currently left in the dark, not knowing what the cause of the problem is, and we are using lots of time problem solving and finding out the cause could be, whether it could be our settings or other causes.
Please respond Plex!
Yep I am on the same server version, and experiencing exactly the same issue with sync.
I have reported the issue to Nvidia customer service. If more people do the same, perhaps it would make greater impact.
I have not found Plex customer service, only this forum.
Hi, the same for me. Sync process is blocked at 50% and waiting for download
Please Plex help !
