version build-893-arm64-play
2017 RAM with Uconnect 8.4 NAV head unit - SW version 17.51.21 (1 newer rev available that only has GPS fixes, per FCA)
OnePlus 6T with OOS 10.3.9 (Android version 10)
All other audio playing apps display correctly (TuneIn, RadioParadise, Podcast Republic, Plex, Spotify). Tried AIMP to see if it was my local media files themselves - Info displays correctly with AIMP.
I have owned the truck for 1 year, and only "Unknown" artist/album has been displayed over various OOS 10 and Poweramp versions (back to at least build 871). Poweramp fresh installs, library rescans, cache deletes, etc have not changed the "Unknown" problem. Poweramp has always displayed the info correctly on my Pioneer AVH-X391BHS head unit in another vehicle.
The attached images are from AIMP (the good display) and Poweramp (the failed data display).
Why is this hard? I'd be happy to support some debug and beta testing.
