Thank you for including this information. This is an issue on Apple’s end. How long have you been experiencing this for?

This issue was across yesterday after noon, I did however get a build to Apple yesterday evening.

The issue is occurring this afternoon.

I had this problem intermittently on Wednesday and Thursday.
Guessing it’s an Apple issue..although they’re not admitting it on their ‘status’ pages..

Unfortunately Apple’s servers seem to go down from time to time and the only thing we can do is contact their support and suggest you do the same.

Strange this morning

Build 1 → mimetype error

Build 2 → Success

Builds 3,4,5 → mimetype error

(all same app etc)

These issues appear to have died down. We’re hoping Apple has fixed things on their end. Please let me know if you run into any more problems.
