So we're trying to distribute an app to one of our investors. He was previously in our internal testing group, and we have since switched to distributing the app using external testing via public link, so we've taken him out of our internal testing group and started to distribute the app that way.
However, when he tries to download the app, he sees this on the app page inside of testflight:
Tester Removed
The developer removed you from the test program
So it seems like somehow his status as a former internal tester is overriding the public link.
How can we solve this? It's extremely important to get him access to the app.
