Hi, I'm facing this issue for 2-3 days now and I have submit a ticket FB9959411. A lot of people are facing this issue ... could it be related to this new warning on AppStore Connect asking to accept latest Apple Developer Program License Agreement ? Review the updated Paid Applications Schedule. In order to update your existing apps, create new in-app purchases, and submit new apps to the App Store, the user with the Legal role (Account Holder) must review and accept the Paid Applications Schedule (Schedule 2 to the Apple Developer Program License Agreement) in the Agreements, Tax, and Banking module. To accept this agreement, they must have already accepted the latest version of the Apple Developer Program License Agreement in their account on the developer website.

Hi, I still have the issue with application using Notification Service Extension :/ I sent a feedback. BTW putting external testers solves the problem as said by @raphaeldcout
