Sadly bits fall off depending on which browser you use. Firefox seems to have fallen out of favour and can no longer share. Chromium efforts still seem to work OK. I have sometimes found that faking my browser agent helps with stability ... which is sad and possibly rather disingenuous.
I must get around to spinning up a Jitsi jobbie. BBB should be my favourite but is a non starter due to elderly software in the stack. I need to take another look at all this stuff.
