The only way to fix an app is to push an update. So yes, if there was an issue it could be rectified.
To clarify here:
It sounds like people are experiencing an issue in which they enter some strings for adMob. It works. Then the make changes to the app, and then admob stops working. But, if you renter the values things start to work again?
Does that sound accurate? I want to have clear info to pass the engineering team and a project they can test with. Does this happen with all projects, DnD only or StP only?
