> My Forerunner 935 is basically the same story today. I can't do anything on it via the mobile apps.

I also have a 935.

Today I've so far recorded two activities. I can see my heart rate, and RHR for the last 7 days, I can see my training status (including VO2 max, lactate threshold, etc), I can see footsteps taken today and over the last 7 days, I can see my calendar, I can see my calorie burn today and over the last 7 days and I can see details about activities recorded on the device all the way back to December 18th.

The device isn't at all crippled.
