Charger Status Display Doesn't Update / Need To Know What Colors Mean

When navigating to an EVgo (or EVgo eXtend) charging station the next stop tile showed a segmented circle with 2 blue & 2 grey segments as soon as we started going to the station. Over the 90 minutes or so that it took to get to the station the display never changed.

At other times I’ve seen the segments colored in green.

When we got to the station the segmented circle didn’t match the “facts on the ground” — it would be great to know:

1. Is it supposed to be a real-time display of station status?

2. What status is being reported?

3. What do the colors of the segments mean?

4. How often does the display update?
