Resound 3d app - problem

have been happily using the 3d app on pixel 6 for years. all of a sudden i’m getting a battery low warning (one red dot) on my left aid (right aid shows 3 green dots) whilst using the streamer 2. if i turn off the right aid, then back on, i get 3 green dots showing - if, on the other hand i simply place it in charger, then take out again, i still have low battery.
in general, if not using streamer, i have two green dots at the end of the day.
i have; uninstalled / reinstalled 3d app, turned off / on streamer, etc., yet the problem still remains?
anyone have similar experience, or suggestions?
