The Testflight does not update the build after it is assigned to testers

Hello community!

I recently ran into a issue that I don't understand. I have upgraded the version of my mobile project (20.3 - > 20.4). After that, I built the build using XCode and uploaded it. Then I waited until the build status changed to "Ready for submission" and assigned the build to the test team in Testflight.

Issue:

A messages about the availability of the build has been sent to testers, the build has the status "Waiting for Review", but the app has not been updated in the Testflight app and testers see the old build(20.3)
