Error in upload builds on TestFlight/AppStore. I am using Xcode 9.3 and error throws:
An error occurred saving your changes to the Apple database. Exception occurred when creating MZContentProviderUpload for provider. (1004) An unknown error occurred.
Anyone help me why I am getting this error?
Looks like something's up with Apple's servers. I am getting the same error so this confirms that. I was able to upload my app earlier today but from the past one hour, it's not working.
UPDATE: Although the upload went through for me, the app is still stuck under processing. Looks like their servers are still acting up.
