I have this same issue. OLD app that I removed several years back, I renewed my developer account, uploaded new version of app and get this message from test flight. New apps that I uploaded to my account work fine, but not the older apps even after uploading new versions and having them approved for testing.

im having same issue with an older app that had been removed from sale and now im trying to test a new version.

I have contacted apple support a few times about this, they supposedly have send my case to someone higher up the chain and I'm still waiting to hear back from them. There are 2 or 3 posts on these forums with other people in the same boat, I'm hoping once one of us get it fixed the solution is posed in here so we can at lease direct apple support on what needs to be fixed.

LOL apple replies to all my requests saying its not working because there is an issue, but they never say what the issue is. NO ****, why do you think I'm contacting you! Why do they even respond if they wont even give a response or read my support request?

WOW, now I submitted the app for approval to the official app store, the app is approved and then instantly changed to removed from sale. what is going on?

were you able to fix this issue?

I released new version, its now showing ready for sale status, I still cannot download from app store nor test flight builds.

OK, I take that back. I released new app version to app store for review and selected to let the developer choose when to release. They approved the app for developer release... still no test flight builds working. I actually released the new version of the app that was approved for sale... app not available in test flight as well as apple app store. around 6 hours later, the app is now available in both app store and test flight.

After submitting version for review to Official app store and app was reviewed and approved. It took another 2 or so days before I could see the app in the app store or submit test flight builds.

try going to privacy settings and then turn off the setting to allow apps to ask permission to track you, then turn on the option to allow apps to ask to track you. This worked for me and the call blocking section showed up right away. However I still am unable to get any apps to present a call screen and ring my phone after they screen a call. (robokiller/callhero)

I have been having this issue as a user after iOS 14.5 both robokiller app and callhero app are supposed to display the call notifications after screening the call to make sure its an actual person but my phone never rings, all I get is a silent notification saying to tap to open the app. strange thing is the developers of said app say they dont know of any issue like this as no one else is reporting this problem. I even did a factory reset on my phone and setup as new and same thing, im missing all my calls.

As an end user I am also seeing this, none of the call blocking apps are able to ring my phone with incoming calls after screening unknown callers. For the app CallHero I get a silent push notification that I’m guessing should trigger CallKit to wake the app and ring the phone but that never happens.
