Ugh, that's awful. I've got a Mini DisplayPort w/ a non-Apple monitor and it sucks to have to unplug and plug back in every time. You're right, it takes an awfully long time as well to connect.

I've not got any issues with Bluetooth thankfully but I do get kernel panics 2–3 times a day where it almost always kills the system and results in lost files, there's no warning at all. Even then, it'll sit there for anywhere between 10 seconds and 2 minutes, then restart... most the time...

Not cool. I spoke to customer about both issues and their advice was SMC reset and also to reinstall the OS (just over top of the existing Big Sur install).

Neither made a difference...

Hey @scaffolder79 did you have any luck with this issue?

I've having the same issue, still...

Thanks,

Ashley
