If its a popular app with lots of competition, if your competitors have a working app and yours is broken then people will jump ship and once that happens hard to get people to go through the hassle of moving again.

Though I'm not an mobile app developer just one of the things I can see as a downside.

This doesn’t make sense - if it’s a hassle to move, people aren’t likely to just ‘jump ship’ in the next few days.
