Hello. Recently I ran into somethings with the Opera VPN. YouTube has given me prompts saying "sign in to confirm you're not a bot" when watching videos with the Europe vpn-setting (and happened to stop when deactivating it).
and I also just lost an entire channel that I used with it. Despite only watching videos, adding to playlists and posting a few insignificant comments (manually typed). Which thereafter lead me to suspect that maybe it was something to do with the vpn or browser that YT's system picked up, because I didn't do or post anything automated and was barely active. So made no sense.
And just to check, I tried using a different vpn while Opera's was deactivated and selected 'Sweden' and there it went stuck with the YT prompt not going away until I chose a different location.
