Going forward there will be no more pro options available when testing? I purchased from the App Store but that’s definitely not making it so the options are available in the TestFlight. Right now I’d pretty much have to stop testing to get the full app (which I have done now).
Syncing between the real app store and testflight environments is a bit tricky. I've got a few ideas on how to solve it, but it's not something Apple supports out of the box.
I'll let you know when I've looked at it a bit more - for now I'd just use 1.0.6 since the latest Testflight version only has some minor tweaks & bug fixes.
