After connecting to Express - Start/Stop Activities replaced with IQ Store

Hi,

Tonight I connected my garmin epix pro 2 to the express app on windows to load some additional music. After finishing, I went to start an activity by pushing the upper-right start/stop button, as usual. Except there were no activities. Instead there was the 'IQ Store" at the top of the list, followed by:

Workouts - empty

Navigate - 

(a bunch of other stuff I don't care about)

After fiddling around for five minutes (again!) to try to get the watch to show up in the express app a second time, I looked around in Express, there really isn't any functionality here that would seem to alter the activities list. There is however an IQ apps button, and in this section I see that the "IQ Store" app is on my device and cannot be removed. This is the second time I saw the words "IQ Store" that I can remember--the first time being what I described above.

So how did this happen?  Why did my activities disappear?
