On our Model-Driven App we have a welcome-screen that shows a canvas-app. This is working fine on desktop but when we tried on iOS/iPadOS the canvas-app wont display and instead an error message appears with "UserInterventionNeeded_CookiesBlocked".
I've found https://docs.microsoft.com/en-us/powerapps/troubleshooting-startup-issues#instructions-for-safari-ios and tried following the instructions but it didn't help.
