Sorry, I misread you. The code for that Redeem field is: VSFcfP3A
That is the end of the public join link. Type it in and TestFlight will add the app. Or open https://bitcoinsaving.fyi/testflight/ in Safari on the iPhone and tap through to TestFlight, then no code is needed.
The sandbox login from step 3 is a separate thing and will be posted here before you get to the purchase step.
