[NeoCZ]

Both tablets I have in signature shows this problem. Don't know if it's related to any of my settings, but if I load the app, wait few seconds just to be sure everything is loaded properly and then change tabs by tapping on them (my first tab is Collections) I get this. I've also added few more tabs that might somehow cause this. Also it seems it only happens if language is set to Czech / Čeština, If I set i to English, it seems to be OK.

Try this:

Use my backup, launch the app, add tabs Umělci, Alba, Žánry (Artists, Albums, Genres), relaunch the app, be sure to use Czech translation. First tab that shows should be Kolekce, tap Skladby and now you can't change to another tab anymore.

Hope I've provided enough information for you to be able to reproduce this...
