Versa 2 Firmware Version 35.72.1.9
Uber app installs but will not complete the authentication (login) process: it appears to have been resolved in the past, but the issue has reemerged and none of the previous answers resolve the problem.
I have also been having the same issue. Click login link on the uber app within the fitbit app, it starts to load another page then goes back to login link. App is broken.
