REMOTE PLEX Media Player User’s Movies & Shows are Not Playing, Please Help

Server Version#:

For a long time now, waited a long time for the problem to magically solve itself, that it never did, when we go to play any of REMOTE PLEX Media Player user’s movies/shows, there is the spinning indicator, with the message- .checking connection speed to data; while I have waited minutes, I have not waited for it to time out. No problem with downloading Amazon content & roommates say REMOTE PLEX Media Player user’s filmed videos work, as PICS also do.

We have had this problem many times before, but I do not remember this message before, & the REMOTE PLEX Media Player user has two-servers setup & we have access to both. In the past, he says it is his content problem & it had become fixed. We have also had problems with our BLANKING AT&T WiFi/Internet, as we have discovered this in the past, I assume has to do with AT&T not maintaining our high enough performance level of WiFi/Internet, we pay for.

Please Help

So is it the fault of:

The REMOTE PLEX Media Player user’s content problem (both quality-amount)

or

What I think is the problem, AT&T not maintaining our high enough performance level of WiFi/Internet?

I’m finding the issue that the app or file crashes when moving from wifi to cell.

It never did that before.

Plex server has all updates, using latest IOS version.

How does that help me, with the remote friend’s movies/shows failing to load-up (if that is right) & play?
