When I have a GPX file on my mobile device, and I click the action "Copy to Connect", Connect fails to create a course if the mobile device is offline (for example in airplane mode). The error message is something like "Oops! Something went wrong loading your courses." It makes sense that loading courses would fail with no internet, but I should still be able to create a new course. The current behavior severely limits the Connect app when using in the backcountry, or other areas with limited network connectivity.
Using Garmin 4.22.2.1, iOS 12.4
