@ivory nope. for some reason Ivory doesn't have the *option* of emails. (first screenshot is Ivory's settings. second is a different mac app. tho that app is multi-platform so maybe mac-only apps don't have the "email" option? that would be silly but who knows with Apple.)
@sararielle Oh it might be based on how you are signed up for testflight for a specific app. Since ours was a public invite, we didn't capture your email address if you just joined yourself. Maybe for the other app you are testing, you provided an email address to get invited?
