I had an iPhone 6 Plus until yesterday running iOS 10.1 Public Beta 4 and backed it up to iTunes and iCloud regularly.
I just got an iPhone 7 Plus and need to update it to iOS 10.1 beta as well so I can restore from backup, but I keep getting a 10.0.3 is up to date message when I try to download and install the Public Beta. I have correctly enrolled my new 7 Plus on the beta site and downloaded the correct beta profile (deleted and re-installed several times, in fact), but it just does not see that there's a beta version out there ready to be downloaded.
Unfortunately I do not have immediate access to a Mac to try updating it to 10.1 via iTunes as suggested by many on various forums, but hope to use a friend's Mac to try it tomorrow.
In the meantime, does anyone know how to fix the OTA download issue? I see online that many others who have upgraded to iPhone 7 Plus are having similar issues.
