I was an Opera user back in the early days. I wanted to give it another try. I downloaded the setup app on my M1 Mac, so this is a fresh install. I enabled ad blocking, trackers blocking, etc. "Save passwords" is enabled. I log into my Gmail and Youtube accounts. However, every time I exit Opera, my logins weren't saved: I had to re-enter my credentials on Google and Youtube. I was also never asked to save any passwords, and none were saved for Gmail or YT.
I thought this might be an M1 issue, so I did a clean install on my Intel MacBook. I did not change any default settings. I logged into Gmail and Youtube, but on restarting Opera the same thing happened.
This is very disappointing to see just as I'm trying out Opera again.
