Pro Tools Bridge 2A – Zoom Input Issue

[RayCervenka]

Did Zoom change something on a recent update? We usually use Audiomovers to send audio to client and PT Bridge 2B to hear back. I tried to send audio to Zoom via PT Bridge 2A and it only intermittently works and poorly at that. I use PT Bridge 2B 24/7 to monitor from Logic Pro without as much as a crackle.
We have two HDX systems and I tried it on a know working system however, Zoom updated upon launching and it too doesn't send audio via Bridge 2A. In "settings" audio tests OK for playback but no input-level even when sending a full-scale test tone from PT.
Both systems are on 6,1's running Big Sur 11.5.2; PT 2022 9.0.

Any suggestions as I've found only one thread on Zoom Support.
Thanks!

Try clearing your Pro Tools cache and see if the same issue occurs.

Thanks for responding.
Cleared the PT cache. Deleted all I/O and set to default. Swapped the Bridge 2A/2B paths. Rebooted with just PT and Zoom up. Still nothing.
Logic Pro working with swapping the paths. Zoom does receive audio from my USB webcam.
I probably should just get out of the stone-age of Big Sur and update the OS.
Cheers!
