In the App Store section the app version is in Prepare for submission.
The build in it is number 3.
I loaded build 4.
The "+" sign on the left of the "Build" Label is missing.
Have I to delete the build 3 from the App store section before set the build 4?
Let's check where you stand:
- you have uploaded Build 4 to the Appstore ?
- Did you receive an acknowledge mail ?
- In Activity area of AppstoreConnect, do you see the build 4 of the app ?
Then you should be able to remove build 3 ans select 4 instead.
You probably will need to increment version number as well.
