The mentioned way of setting up complications does not work. We can't create the identifier according to the guideline mentioned in the WWDC session. https://developer.apple.com/videos/play/wwdc2020/10049/?time=1021 Timestamp: 17:04 Error: An attribute in the provided entity has invalid value An App ID with Identifier '.watchkitapp.complication' is not available. Please enter a different string. To clarify - the non masked identifier is not used on another property inside our dev program. Without creating the identifier our tests result in not working push notifications. Error message while testing: discarded as application was not registered. Is the way mentioned in the WWDC session still valid? BR
