Can't play duels anymore

Since sunday I can’t continue playing my duel run anymore. At first I thought about a random bug and try to restart / launch from mobile but nothing works.

Every time I try to launch a new game in my duels run I recieve the same error report stating “an error has occured, please try again later”. I’m at 1 win / 1 loss so I could still continue the run.

Altough I think I could just forfeit the run and go for another one since 150 gold isn’t that much but I kinda want to keep playing it.

Has anyone experienced that bug whatsoever ?
