This issue seems to have been fixed now.

There seems to be a wider issue since also a bunch of other users have encountered similar issues today (including myself): https://developer.apple.com/forums/thread/788946 So probably Apple needs to fix something on their side before Apple Intelligence related stuff will start to work again on the latest beta versions.

Same here. This issue seems to have also broken all Apple Intelligence related on iOS 26 beta. Yesterday everything was working normally.

Same problem here. Same code works on iOS 16 but not on watchOS 9 (tested also on watchOS 9.2)

Same here and only on watchOS

In my case the Overview part of the Sales and Trends section seems to be the problem. You should be able to access your sales data by using a direct link to your sales chart: https://appstoreconnect.apple.com/trends/sales?measure=total_tax_usd_utc

Same issue here. Works fine on watchOS 7 but not on the latest watchOS 8 beta. Same code works just fine also on iOS 15 beta.
