the official fix for the "the following content is not available on this app, please watch on the latest version of YouTube" error is to use
the gmscore patch which replaces the use of vanced microG with the microG that revance maintains
but none of the revance apps posted here is using the fix (exept for the one kirlif posted)
you you either have to wait for them to use it or patch your own with the manager

"the following content is not available on this app, please watch on the latest version of YouTube" No matter what option I enable / disable / clean install, whatever.

The only way is to patch YouTube 19.09.37.1544809920 using revanced manager usin gmscore patch

Second @RioGunawan. Those who are getting the "the following content is not available on this app..." error, navigate to Settings > Revanced Extended > Miscellaneous and disable "Spoof player parameter". It worked for me. I also disabled "Spoof app version", but I am not sure if that makes any difference here.

This worked for me! I only had to turn off spoof player parameter and it fixed the issue

Turning off "spoof player parameter" just worked for me. Thanks for the info.

It doesn't work. Video stops after 1 minute or so. Seems like patching is the only solution.

Running pretty much continuously for 16 hours now with no issue after turning off the spoof.
