YouTube sign in issues since reset

Brave started playing up after about 18 months of install as it became very slow & laborious on FB & other sites. I ended up having to do a total reset to no improvement & then delete
& reinstall , everything is great apart from google, when using youtube i have to sign in to google every time & after about 20mins it signs me out. I have tried various things in the brave settings & even turned the aggressive ads down but this is the only site that gives me such annoying problems :face_with_symbols_over_mouth:
I know its prob a trivial issue but this has been a bug bear for months now & i cant find any help on the net to fix this , plus im a complete PC non techy bod
