Couple frustrations that I need to work through with #Vivaldi:
When I switch Gnome (Ubuntu) to dark mode in the evening, Vivaldi doesn't switch to a dark theme. Firefox does, so I'd assume this is a Vivaldi issue. 🤷🏻♂️
Some settings aren't synced between devices. Such as search engine choice, what the address bar displays when typing etc. This should be a one off thing as I get setup, but it's frustrating none the less, and things I'll need to re-do every time I get a new device.
