I have a question about this topic since I have read on sites that I can not do it and on others that I do.
I have a published and active Google Play app, I have changed Admob with my ID, I would like to know if I can also change the package ID or bundle ID and simply update my application after this. Can it be done or does the package ID have to be the same? I do not want to create a new app, which is already published and I'm only interested in an update.
Can it be done?
