App shows blank screen when Mobile Data is on.

[JenWgtn]

I just got the Versa and updated my old Fitbit ios app to the latest version. When I turn on 'use on data' in the app settings the app won't even open - it just black screens then returns to the main apps page. When 'use on data' is off it opens fine but doesn't sync anything.

How can this be fixed? It's the reason I stopped using Fitbit years ago and don't want to have to return this one after 2 days

Hello @JenWgtn, thanks for joining the Fitbit Community, it's great to have you on board. 

I appreciate you have brought this to my attention. At this moment I would like to ask you for more details about your issue and a screenshot where you're enabling and disabling "on data". This will be very helpful for me to determine what we should do next. 

Thanks for your patience and understanding, I'll be waiting to hear from you.

 This is where I’m turning on data. In Settings. On iPhone 6S running 11.4.1.

note: I can no longer open the app at all, now that I am on the WiFi. This is all I get before it crashes:

By the way, I tried to do this, too.
