Hi ED....can you tell us if your Using IOS or Android? I see in your post above that your showing GO Fly.
I have the Iphone 8 and use Fly App and I can't look at the About option either on the Fly App when
using Mavic Mini-2.
If you updated to Fly version 1.2.5 , its easy to check, search for it in the App Store, and when you find it, tap on it to view the details. If it says "Open", your updated to V1.2.5, if it says "Update", then your on some previous version..
As I noted previously, if your using a later version of Fly, and it used to say About or whatever to check the version, its under Profile from the Main screen, Settings and On the left, the top of the menu should start with "Aircraft Firmware Update", you should be able to scroll down by swiping to the bottom of that menu and under
Log Out, the current App version information is displayed..
If you cannot see it or scroll to it, I would delete the app and re-install.. be aware if you do that, any flight data for flights up that point will be deleted, unless you save it to AirData or some other means of backing , flight data.. probably sync to DJI..
