My Phonak Slim 90s doing strange things today

Earlier on today I got the powering off, followed immediately by the powering on jingles in my right ear, but didn’t get the aid off tone. Neither aid turned off.

I thought this was strange, but then this evening I was streaming a Dr Cliff video and adjusted ambient balance to the right - All ok, but then when I turned down my aids volume (my aids are set up so that the button on the R aid increases the volume and the L decreases it) the ambient balance slider moved to the left.

Any suggestions? My aids are 8 months old.
