Remote library unavailable only on FireStick 4k

I rolled back to 7.23 and all works. Took me a few tries but here is what I did.

I already had Downloader on my firestick 4k
I downloaded the free version of ES File Explorer on Firestick. ignore the upgrade request
I then downloaded kepler-armv7a-amazon-stdExo-7.23.0.13018-f9b0a0fb.apk to my laptop downloads folder
Then use ES File Explorer to share your Firestick file system with your computer over wifi, it gives you a URL to connect.
I used FileZilla, a free FTP client to move the file kepler-armv7a-amazon-stdExo-7.23.0.13018-f9b0a0fb.apk from my computer to the Files folder on Downloader on the firestick
Then open up Downloader on your Firestick, navigate to files folder on the left menu and you should see the Kepler… file there. Click on it to install and open.

Note/Issue:

I tried the Google Play version of Plex first, but it was never showing up in the Apps folder on Firestick, so I uninstalled and installed the file above which is for Firestick.

It also does now show up in the Apps folder, so to use Plex, I hit the microphone button on Firestick remote, say “plex”, and it brings up Plex like it wants to install it, but when I click on it, Plex opens up and is fully configured with my account info etc and works fine. Since working, i can deal with the extra voice command step.

Also, in the settings on firestick, you may need to allow 3rd party programs to install files on the firestick. I already had this turned on due to some other stuff to run, Downloader may give you an error message and direct you to do this if you have not already enabled 3rd party apps.
