Bug: Inviting external people to the Release Channels for my Meta Quest 2 App doesn't always work

Hello,

I have the issue that when I invite external people to my Meta Quest 2 App through the Alpha, Beta or RC Channel, they can not access the build.

They always receive the invite and can accept it, and the app will be shown in their Preview App. However, they can not install it through their App Library, and they can not access the Meta Store page of my app (it is saying "Whooops... Something went wrong".

Throwing them out of the User list for the Release Channel and reinviting them usually solves the issue, but it is a blocker and a nuisance to people and some of them may not be able to look at my build, so I really need this fixed. Any ideas / workarounds that don't require resending the invite?

Thank you!
