Did the app ever get updated to show the Giant power modes instead of numbers?
For what it's worth, the modes (not displayed) and associated numbers (as reported to my Garmin 830 from the Giant field) on my 2020 Reign are:
0 - Off
1 - Eco
2 - Eco+
3 - Normal
4 - Smart Assist (Auto)
5 - Sport
7 - Sport+
I have no idea what happened to 6!
