I recently submitted what I THOUGHT was a finished game to the Appstore, but it was rejected because the ads showed up as a “test ad” which is considered “unfinished”.
Do you have another Ads block somewhere - possibly you have one that got overlooked? If there is any Ad block anywhere in the game set to Test Mode, all ads will stay in test mode.
If that’s not the case, please DM me a link to your game and I’ll take a look and see if I can figure out what’s going on.
