And notification of bugs and regressions?

I imagine this is the right place, here is one new one.
Since recently, if I open the Android app and chat to partner after opening his profile, when he invites me to a tournament I hear the sound but am unable to accept because the screen is frozen exactly half way down between his profile plus the start of tournament description and then "Report Abuse" plus the Samsung onscreen keyboard. I can send a screenshot if it helps.
