I need redeem code for TestFlight on iOS

Have anyone redeem code for TestFlight and doesn’t need them ?
I used my code on friend iPhone and I can’t use Eora on my iPhone. Support of Eora can’t give me next redeem code.
Maybe anyone use only android and can give me code.
I write to support 2 months and contact with them is horrible...

Well at least you got A code - I have a shiny paper-weight as I have an Edora 3D but no app to use it and no code or ever a response from developers.

I do not understand why the app is just not available - anyone without an Edora 3D cannot use it and anyone with one is going to know/understand that it is in development.

Has anyone anywhere got a Testflight invite? If so how did you? No one at Eora is answering mail or messages or posts.

I got my Test Flight invite as an e-mail. It arrived in my inbox while my Eora was in transit shipping to me. I live in Colorado, in case that matters at all. This all happened about a week before Christmas.

Yes, well, if I was sent one at that time, I can't get it back now. I don't see that I ever was; certainly it never made it to my mailbox, and it's not in my spam log.

I received two unsolicited emails, one from "TestFlight" [no_reply(at)email.apple.com] with the subject:

 EORA 3D PTY LTD has invited you to test "EORA 3D"

... and another from "Rich from EORA 3D" [rich(at)eora-3d-a30a2cd417fc.intercom-mail.com] with the subject:

 iOS BETA RELEASE - EORA 3D

The latter included instructions; the former had links to the TestFlight app, and presumably to the EORA 3D app.

The emails arrived on 2018-01-08; the scanner arrived on 2018-01-22 (near St. Louis, MO).

Eora generated a Testflight email for me, after many requests on their site chat. Indranil sent it. Boyfriend was able to install on his iphone. I have yet to actually attempt a scan.
