Okay So I was able to submit my app for review. I guess you cannot wait for too long after you submit your build. I have no proof of this but I think if your build is inactive, you cannot use that build to submit an app. Here is what I did to solve my issue
- In xcode I changed the build version, not the app version,
- Archive and validate
- Submit
- While the build was still “Processing”, I went back to my apps new version page on iTunes Connect
- Choose the new build and submit for review.
Dont let the build become inactive.
Good luck
