Android app silently loses connection still happening
Recent versions of the android app are still silently disconnecting from Wi-Fi. Reverting the android APK back to version 3.1.6 fixes the issue, although I do not know exactly which version the issue began.
Bluetooth does not seem to be affected even in the most recent version.
https://community.unifiedremote.com/topic/711/android-app-silently-loses-connection is a similar thread and the issue is still persisting.
Interesting, I didn't realise there was a version where this wasn't happening. I've just installed it, but it's closing the app whenever I try to start a custom remote. I might need to do some digging there. Are you using the latest server and this APK successfully?
I've never used Bluetooth for connection, I don't have a card at the moment. Are there any disadvantages connecting that way?
