KOMOOT is lost under 19.20 - and no Chance to install it via GC

Komoot App was gone suddenly. I can re-download it into GC - but it’s not possible, to install it!!! 
Removed GC from my iPhone, reinstalled it, reconnected my watch after removing it… did all these things! But no way!!!

@GARMIN: PLEASE REPAIR THAT BUG!!!!
