REX / TESTFLIGHT
The next Rex.
A little earlier.
Any active permanent authorization that unlocks Rex qualifies: permanent Forward or Rex in-app purchases, permanent website purchases, and permanent admin grants. Subscriptions do not qualify. The code goes to the authorization email; the TestFlight invitation can go elsewhere.

Verify the email linked to active permanent access; the TestFlight invitation may go to a different email. If you already have an invitation, you can confirm a change after verification.

Test builds may have unfinished features or bugs. Keep a backup of important data. Each permanent authorization has one application slot across the website and existing channels. Changing an invitation requires confirmation to remove the previous access before a new invitation is sent.
Verification emails: wait 60 seconds between requests, up to 3 per hour. Each eligible permanent authorization allows at most one invitation per day (UTC+8); changing the invitation email also counts.
