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?
