On the Mac client there appears to be an issue since the latest battlegrounds update causing what appears to be some kind of click delay within the client both within the menus and in game. This makes playing battlegrounds particularly difficult as it is sometimes impossible to click on cards.
I have tried the usual reinstall, changing of graphics settings and resolutions but nothing seems to fix it. There appears to be no issues when playing via Windows or Phone. Only happening via M1 Macbook.
