I am a big fan of this browser since I found it, but recently I have been having an issue in which all of my accounts on all of the websites I frequent are being signed out when I exit Opera GX.
Essentially, whenever I fully close the browser all of my accounts have to be signed back into, when this wasn't the case before. Almost like when the browser restarts it forgets everything I had set beforehand.
A good case of this is with YouTube, the most frequented website. Everytime I have to sign back in, but on top of that, the dark page settings I have in the browser and on the website both are being forgotten. This didn't use to happen, and I'm not sure why it started.
