I am on IOS latest 11.2 and latest GCM. No matter which IQ app I want to change, in settings when I save it asks Open outside GCM? and of course I cannot save from Safari...
This is currently being worked on as a known issue within GCM on iOS and certain language variants. I have no knowledge of the fix time but it is being worked on. The work around is to use Garmin Express to do what GCM on iOS cannot (currently) do.
I agree totally with ColinSainsbury.......I contacted Garmin last week with this very issue and it's in the hands of their "techs". Yes, express is the workaround albeit no where near as convenient.
The other workaround is to set your phone’s region to United States. You can leave the language as-is and change the 24-hour time format and temperature units back to their previous settings.
There are so many threads about this. I find it kind of sad that Garmin isn’t doing anything to communicate this workaround so that everyone can take advantage of it. I guess it’s the standard procedure of not trying to draw too much attention to a problem in the hopes that most people won’t notice.
