by following @Erel Update on this Post https://www.b4x.com/android/forum/threads/background-location-tracking.99873/#post-993226 targeting Sdkversion = 34, if you have a foregroundservice that do media play back in the background you will need to add this to your manifest in order to migrate...
None of the foreground service types seem appropriate for what the keeprunning service is doing, so I have just left it as mediaPlayback. I don't know if that will cause an issue when I upload to the store, but hopefully not
