Thank you for the welcome and the info! I hope that my additions provide enough information for some assistance. I love Manjaro and I think this is the only snag.

I was looking through your issue on the Thinkpad T450 using bluetooth to connect to devices. I also have a T450 and though I can connect to my bluetooth headphones. My Manjaro Gnome install is about 1.5 weeks old with all patches.
I won’t say things are perfect because I am diagnosing the following issues before I file my own post:
Switch devices seems to be flaky (e.g. the Edifier Headphones I have will sometimes connect in a headset mode and not stereo hifi).
Youtube videos will suddenly freeze in full screen mode in Firefox. Come out of Full screen and video will continue to play.
That being said I noticed your T450 bios has not been updated from the original 2015. I recommend you update this first:
I will keep you in the loop as I figure my way through the issues. Note that I remember having some similar issues with bluetooth with my T430s and x230 on some Manjaro builds. So I totally get the fustrations you must be feeling when you have a laptop from 2015.
Thanks so much for the heads up about the BIOS! It’ll be my first time updating something like that. I don’t know if it’s unfortunate, yet I’m only running Manjaro so it’s unlikely that it’ll be easy.
I’ll take this issue with t450 and lenovo to keep track of these types of things.
On another note, I also have this problem:
Youtube videos will suddenly freeze in full screen mode in Firefox.
So what I was reading on the Arch forum is some people are indicating that PulseAudio got broken on the latest release (which is causing Bluetooth to not connect dependably). The person in the below post downgraded their packages.
In my testing I did use the ‘bluetoothctl’ to connect to my headphones. I also issued the command to trust the device from command line. After this sound work correctly. But then after I reboot the laptop and try to connect to same headphones via Gnome Bluetooth controls it fails to connect again.
So if this is a regression with Pulse Audio, I’m trying to figure out whether there is a patch coming to Arch.
I’m also on version version 13 of Pulseaudio (so assuming this is part of the problem).
To be 100% honest I just switch this month from my Thinkpad x230\T430s (3 years on Manjaro) to the T450 and T450s as my daily drivers. So when I read through the thread in ([DOWNGRADED] Latest updates broke Bluetooth / Kernel & Hardware / Arch Linux Forums) I wonder if other updates to software are contribute the bad bluetooth behavior.
So perhaps what we should be looking for is whether an official bug has been filed on this issue?
