I had similar behavior on my BRIO journey after 20H@... Firmware fixed that for me.. I noticed some of you are running 2.2.50, 2.4.56.0 is the newest version found here.
That is for the 4k version not the streaming. If you have the streaming version and having issues wonder if it will let you flash the 4k firmware and that would fix it? Obviously a risk if it bricks it. I can't even find this "streaming version" on the Logitech website?
Just did some quick research on this... and found this "Streaming version has a year of X-Split and is targeted at consumers, 4K version is the same camera but targeted at businesses (hence the plain box)."
I don't think the hardware is different from 4k vs streaming "version" I think its safe that everyone can run 2.4.56.0. Now that's my opinion. Other hardware generally won't allow a flash of wrong version firmware. What brave person will test my theory, lol.
