iOS app 3.99 crashes when clicking on “update Ionic”

[Blakinsop]

My Ionic syncs to my iPad just fine. However, when I try to click on “update Ionic” (with the new firmware) or select the Ionic itself in the app, the app terminates instantly. 
This is only since v.3.39. 
Any advice?

Cheers.

Thanks for the details shared in your post. I appreciate your efforts and recommend confirming if you see an update available for the Fitbit app: How do I update the Fitbit app? 

By the way, I've moved your post to iOS board so we can keep our forums organized.

Hi, I’ve just updated the app to v.3.39.1 (1034) and all is well, thank you.
