Restoring the purchases in our app also worked for me.
Feedback ID is FB8750506
Displaying the price with NumberFormatter doesn't solve the issue because prices in Germany and the US are different.
And it doesn't depend on the Xcode version. Happens with Xcode 11.4 also. And with Xcode 11.4 I uploaded the current version to appstoreconnect. The current store version has no issue.
Even installing the app from TestFlight doesn't solve the problem.
I sent a feedback to apple. Hope it will be fixed soon.
