Hi. For about 3 days I can't get video/audio calls to work on Facebook or Messenger apps. I make a call, it rings the other end, they answer but I get a black screen (the camera and mike are on - I can see MY video) and that's it. Sometimes I hear it ringing out, sometimes not. They can't see or hear me and I can't see or hear them. Same happens on the equivalent browser websites.

I completely uninstalled then re-installed both Facebook & Messenger apps, but the problem remains. Video/audio calling on Skype and WhatsApp works fine.

I turned off Adguard and Avast AV and tried Brave & Edge browsers but that made no difference.

I'm at a total loss. Any ideas would be most welcome.
