Just did a CMOS reset, but to no avail. Exactly the same problems. iPhone can't connect via Bluetooth, continuity etc. doesn't work, BT is shot after sleep. I can connect to a BT speaker without problems. Before sleep, that is. After sleep, I can reset BT by switching it off/on.
Weird. Are people using BT without issues under Monterey? Sleep and wake are no problem?
BT info looks OK?
