One of my previous builds had a problem that made it through to the Apple Review, which resulted in a banner at the top of the app saying
There are one or more issues with the following platform(s):
1 unresolved iOS issue
The issue was fixed, a new build was submitted, reviewed, approved and released - yet the banner persists.
How can I make this erroneous and confusing banner go away?
In the "Testflight" tab, under "Builds" click the rejected build(s) and then the "Expire build" button on the top right.
