Hello there. On October 9, 2022, Oscarmh published a topic regarding to a bug in battle, in which he couldn't do nothing due to all button locked.... I'm sure it's a known issue. Well, with the new update the problem was solved ... for Windows clients, but Linux client remains with the same error. Sometimes I cant use my windows laptop so I use Linux instead and cant play fully.
Note that the bug always appears after "killing" a pokemon and at that moment, as Oscarmh said on October 9 2022, the only solution is relog. ie. ranked pvp or bosses is impossible.
