Orange bar stopped showing up, on current setting, about ten days ago.
I have the same problem for a week for the current month. In recent months, the orange bar is visible only in the steps and in the other activities is also no longer visible. The same problem with Garmin Connect and Garmin Express!
Garmin support please help !!!!!
I certainly wish Garmin would respond to this issue!
You have to contact Garmin's Customer Support directly. They do not provide any support here, on the user forum. The forum is mostly just for the mutual help between users, and in this case we cannot do much for you. It works fine for most people, so not a general problem. More likely an issue with your account that only the Support can handle.
