As per the title. Duels are bugged, everytime I try to do one I end up with this error message (see picture below). As you can also see, the match is still playing in the background.
This in turn uses one of my 5 daily tokens.
For the most part it seems to happen only on my first try of a duel but I have lost more than one token before today.
Game is fully up to date (v 36.3.0).
Samsung s22 Ultra, no updates due.
