Who is your celluar provider? We were tracking an issue with one carrier, but it was resolved. We're not aware of a carrier specific issue at this point and any insights you could provide would be very valuable.
I don't see an answer to this question but I have an iphone 7 using Verizon and have to reload the app every few days.
We are aware of a few issues causing app crashes on the iPhone and are working to fix them with new versions of the app. Thanks for bearing with us while we work through the issue.
