Is everyone that IS having luck force-updating on iOS15 (or newest MacOS)? I'm holding out on 14.8.1, and I'm at least 2 FW revs behind @ AB52 (not 4B66). Wonder if that's a secret requirement.
try
connecting the case + airpods to a charger
open case and see if settings sees the airpods
then leave for 20 mins
take out AirPods
and check version
that worked for me
