On an Instinct 2X I loaded a 45k course (Trail Running). Map was shown on the watch screen. After I pressed the start activity button, the map suddenly disappeared. Fortunately the activity was fully recorded.
The same course (although different gpx import) worked one year ago without issues, similar distance course also worked correctly. The only difference visible by me is that the course with the issue contains waitpoints (wpt tags in the gpx file).
Is there any knowledge regarding this issue? Is there any "rule" regarding the imported GPX track which would prevent this?
Thanks
