What is the reason you cannot sign in to Unifi 2.0?
Your Unifi UPB is currently what version?
My unifi UPB box is 1st gen, also failed to upgrade 2.0. The system update showed "failed".

Not mine though, I'm just helping out someone to setup.
No idea which gen, still new and only installed few months back. Already update to 2.0 but when trying to sign in, it ask to sign in using the previous version.
Thanks... Hopefully the account migration complete soon.
i had trouble initially but succeeded in the end.
not entirely sure what happened, but i think...
. the unifitv app on phone was 1.0. need to go to playstore, install 2.0.
(2.0 doesn't auto replace 1.0, u need to do manually; if u try to use 1.0, it will "fail")
. verify 2.0 by email id.
. install 2.0 on any device, it will ask for approval, show QR code
. open up 2.0 on phone, scan the QR code, cilck yes, done.
. uninstall 1.0, not required anymore.
i have 2.0 installed on pc, 2 tvs, unifi box, all ok now.
hope this helps!
