I've uploaded a new build 0.2 (build 3) to the TestFlight platform, and invites have gone out. But when they click on the invite it takes them to a previous build 0.2 (build 1) (which I've deactivated. So no-one can install or update the new build.
Attached are screenshots of what this looks like when I invite myself to the tester group. I've tried deleting the. old version from my phone so that no versions exist on my phone but that doesn't help.
