I can't upload updated version of the app on Testflight

Question

Let me describe my issue in time perspective:

• I got invited to AppStoreConnect team to my e-mail. This e-mail has never been in Apple system before;
• I accepted an invite and received Admin rights;
• This account already has an application in place and I want to upload it's new version on Testflight for others to test it;
• So I logged in to this account in my XCode through Account page. Login was successful. Side question - I believe once you get invited to some AppStoreConnect team, Apple ID is created automatically for you, right?
• I put our application Bundle identifier in Signing & Capabilities and that's where I start to see 2 errors:
  • Failed to register bundle identifier. Change your bundle identifier to a unique string to try again
  • No profiles for BUNDLE_ID were found.

EXPECTATION: I thought once I get enrolled into AppStoreConnect team with full rights, I will get access to all bundle ids that my team has and I will be able to work with applications using their true bundle identifiers

REALITY: It seems that automatically generated Development and Distribution provision profiles and certificates know absolutely nothing about any application our account has. Basically - if I take any other Apple ID account and use it with our app, I will encounter the same issues.

Please fill the gaps in my understanding - what do I need to do to make apps from our account visible for me.

NOTE: I emphasize - it is important for me to operate as an owner of the app because I want to upload it to Testflight. So changing bundle id to unique string is not what I am looking for

Answer 1

In App Store Connect go to "Users and Access" and check all boxes for Identifiers & Profiles including the ones for certificates.
