I'm getting the message shown in the below screenshot: Right now I'm using the "Qualcomm Atheros AR3012 Bluetooth 4.0" driver.Just installed a fresh copy of Ubuntu 22.04 LTS on my Lenovo laptop and the entire Bluetooth system doesn't work (I mean the toggle doesn't work). I've repeatedly tried reinstalling the drivers to no avail. But no matter how many times i try to pair with them, it never succeeds. However, I noticed that on this new update, Windows is indeed able to find my devices but they aren't displayed by their names but rather by "Communication device" and "Speakers". When I said bluetooth wasn't working before, I meant that I could turn bluetooth on but I couldn't pair with any of my previously paired devices and if i removed the devices, it would not be able to re-find them (or any others). So I decided that I might as well go back to the update. I reverted back to the previous build in an attempt to fix the problem but bluetooth was still not working, even after uninstalling/reinstalling/manually updating drivers and a load of other things.
I've been having a ton of bluetooth problems ever since I updated to the recent feature update that modified the way the Bluetooth UI looks.
