Every time trying to submit but some result. Like this
ERROR ITMS-90034: \"Missing or invalid signature. The bundle \'****.******.****\' at bundle
I resolved many times
1 check AppleWWDRCA certificate if expired or not.
2 check fields for always trust by double click the distribution certificate in keychain.
3. I was using another distribution certificate from same name with another expiry date.
4. update/delete previous distribution installed certificate
