Invalid WatchKit Support - Xcode 10 - iOS 12

Question

I'm trying to send the update of my app for ios 12 with xcode 10 GM.

But every time I finish the upload of the .ipa file after a few minutes I get an error email with this message:

We identified one or more issues with a recent delivery for your app,"APP NAME" We identified one or more issues with a recent delivery for your app. Please correct the following issues, then upload again.

Invalid WatchKit Support - The bundle contains an invalid implementation of WatchKit. The app may have been built or signed with non-compliant or pre-release tools. Visit developer.apple.com for more information.

Can anyone help me?

Thanks

Apple had forgotten to update their backend as was suspected. Resubmitted without even cleaning (changed just the version number) and it got processed.
