Have exactly the same issue (even with Xcode 12). Hope this will be solved soon as this is a really huge blocker.

I have exactly the same issue! The background color will change with any color except .white. If you choose: datePicker.backgroundColor = .white it still get's the grey background. Additionally there is no way to align the date (text) in the field. Doesn't matter if you set it to left/right, it's always at the left side.

As Apple is not doing anything about this issue it might be the best to inform the publicity about it. I mean how can they not take that serious?! Loosing a lot of confident in Apple again..

Had exactly the same problem! Solution: Make sure you really had filled out every required forms in AdMob. In my case the payment data wasn't filled out!

Still not working! Do the Apple Developers sleep the whole day?
