Hi Troy,
Using auto-submit on receipt page works fine.
However, if I auto-submit immediately, the authentication request will fail because it seems the device account created in the previous self-registration page has not entered the Guest Device database yet. (it might need some time, I guess)
If I put a 2 seconds delay in the auto-submit, everything works fine: the service for the authentication request can find the device in the Guest Device database, so the authentication succeeds.
Any idea?
Thanks,
Peiyong
