I checked the version status on my phone and saw that I could now do the update. I probably should have done it from my PC, but I did it from the phone app. The update never completed and I couldn’t connect to my rpi4. No real problem; I downloaded the software and flashed to the pi’s sd card. Everything works fine. I had to rescan the music, but that’s no big deal.
Point: to report that trying to update from the Android app may have some issues.
