I see that 7.1 is out and have managed to upgrade a cap ac2 without apparent issues.
I just tried to do the same with a 951G-2HnD after first upgrading to 6.49.2 which seemed to work fine.
When I choose the upgrade channel I see the 7.1 upgrade and download and install gets stuck calculating download size and no progress is made.
Any suggestions on whether I can complete this? I've tried a couple of times with a reboot in between and had no joy.
I can share my configuration if that's relevant.
Thanks,
Simon
