Missing or invalid signature

When submitting our app to AppStore connect we received the following error:

ITMS-90034: Missing or invalid signature - The bundle 'com.xxxxxxx' at bundle path 'Payload/XX.app' is not signed using an Apple submission certificate.

Solved
We just resubmitted the app.




Probably a hiccup with App Store Connect.. Happened to me the other day as well. Resubmitting the app worked.
Same experience here. Resubmit fixed the issue.
i was getting this too, i tried to resubmit and was still getting it, so i nuked all my certs and provisioning profiles and recreated them (mine were going to expire in the next few weeks anyways) and that worked, not really sure why it happened, but glad others did not have to go through the same things as me.
I got this too yesterday after submitting a different app update the day before. Closed out Xcode completely, went back in, cleaned build folder and uploaded again. Worked. It seemed to be mixing up the two different signatures.
