If searching the directory "Songbook" by searching or scrolling down then after opening a song it is impossible to return to the main menu. After scrolling down and coming back from song you only can open the main menu ( 3 horizonta lines top left) by first completely scrolling up. If you don't scroll up it just opens another not asked for song, again and again instead of going to the home page. After using a search action with a song name it is even worse. Then if returning from the opened song the app is completely stuck, it only want to open the song again, I just left. Sometimes after multiple try's it may return. Mostly I need to complete remove the page first and restart the app.
