UniFi (Network) only partially works.
The app launches and runs, however, if you exit a site and return to the “all sites” list, you cannot re-enter an individual site. The app will register the tap (indicated by the cell turning blue) but nothing will happen.
Logging in/out followed by a re-install does not fix the problem.
They released a new version on TestFlight that works, around 10 days ago. It's linked in their forums (login required).
