Continuing the discussion from Motion+ warbling sound:
Now it returns if I have the temerity to change my sound output (e.g. switch to headphones and back again).
It does resolve IF I re-pair the Sound+ to my Win10 laptop.
[Adding a curious wrinkle, I replaced my phone in the interim and now I can’t get the Motion+ to pair with my brand new Samsung s12 FE.]
When this works I love the sound, but it can’t need this much special handling.
(My last Anker speaker certainly didn’t)
