Hello, I too have been asked to provide some feedback on an app through Test Flight and was curious to know if anyone had insight on the process. Thanks!
I've never been formally asked to test an app for accessibility, but that would be very nice. But just last week a sighted staff member of a local nonprofit organization in which I'm involved, came to my apartment to meet with me about this. I'm helping to test out a new goal-tracking website that this organization is launching. I did this before with another website, but this new one seems to be a bit better in terms of accessibility and general use. The staff member who met with me took good notes, and paid close attention to what I was doing and what VoiceOver and Chromevox Classic were telling us. I've also been testing out something for the local bus company. I received one of their newsletters via email not long ago, and in it was a request for testers. So I sent a message to the email address given, and got back a reply from one of the guys working on this new app. It is an online trip planner of sorts, and fortunately it works very well with VoiceOver and Chromevox Classic. However, I have not received any response to my feedback. So I don't know what's going on. Perhaps they're just being flooded with feedback or something.
