I recently upgraded to Motion 4.21 and am trying to upgrade an existing app to work with iOS11. However, when I upload the build produced, I'm getting the following error from Apple (via email notification):
We have discovered one or more issues with your recent delivery for "APP_NAME". To process your delivery, the following issues must be corrected:
Missing Asset Catalog - Your app is missing the Assets.car file in 'APP_NAME.app'.
Once these issues have been corrected, you can then redeliver the corrected binary.
Any ideas on what might be causing this?
