I have a forerunner 255S and it works very well.
In the app I get training status, even though the criteria for getting the status is not fulfilled.
The criteria according to the app help system is that you need to register at least one run or bike ride with power sensor a week.
I do go for bike rides, but don't have the sensor and I do not run, just go for walks.
So I wonder if the information in the help is erroneous or the software is erroneous?
I try this forum, as it seems impossible to get in touch with support.
