Upgraded to JR4A 26.0.28.
At least 30 seconds wait on opening JR4A with just a white screen displayed, before the top menu turned up.
Says the main library is loaded, but below the top menu (and above the Android 9 navigation buttons) is just white screen.
Reloading main library has same result.
Closing JR4A and reopening results in correct library load with media.
Cloudplay then shows up. Username and Password requested. Playlists show up. Playback works to local device.
Playing Now looks fine, but doesn't have any Cover Art for first three files. I thin it should have. Source Cloudplay.
Later tracks have Cover Art.
Selecting later tracks and Cover Art displays correctly. Slow. So slow in fact that Android piped up a "JRiver for Android isn't responding" message, which I just left on screen initially.
When screen dims playback paused briefly.
When screen went to sleep first time playback stopped, but on re-awakening phone, playback continued after screen slept.
Told Android to wait for JR4A. The screen refreshed okay and playback continued without pause.
At current track end, screen slept and playback stopped without going to next track.
Woke phone. Playback continued, intermittently. Kept getting three to five second pauses with screen blank.
Every time I wake the screen, Cover Art is refreshed instead of the screen just showing what it had before sleeping.
Ongoing pauses. It seems that the popup message made JR4A work better with Android sleep modes.
Sometimes music just starts again with screen asleep, even after pausing for a long time. Like 30 seconds. Could be because I moved the phone?
Switching in and out of Playing Now sees Cover Art thumbnails refreshed, slowly, every time.
Radio JRiver shows up, but no buttons respond. Android says app is not responding again. Android is correct. I can't get any response at all, even after waiting a long time.
Killed JR4A, but notification remains... then Classical music starts to play! It seems Radio JRiver was just taking a veeerrryyy long time to respond. Trying again...
Opened JR4A > Radio JRiver > Try Me. Music played after a while, but there was no indication that something was happening before playback started.
Screen slept. Playback continued.
Waking screen show streaming group, and refreshes Playlists button again. Slept. Repeat refresh.
First track no Cover Art or thumbnail. Other thumbnails refresh slowly.
Slept. Refresh. Getting pretty annoying.
Playback Veerrryy slow to switch to next track. Android says App not responding. Next tracks starts playing anyway. Restarts again. Pauses a bit. Restarts. Screen blanks and playback continues.
Wake screen. Click Wait on popup message. Playing Now doesn't refresh and playback continues.
Screen slept. Refresh on wake.
Stop. Nack button slow to respond out of Playing Now. Search accidently activated. Wait popup message. Screen slept.
So technically it all works. But it isn't a great Use Experience.
