Hi @david - its seems something with the builk .fit file download has gone wrong.
I get a zip file to download based on the selected workouts, but when trying to open the zip file I get an “zip file is invalid” message and the zip file won’t open. Windows 10.
It should be working now. The issue was related to the “disappearing diagrams” problem on the other thread. I botched expanding one of the databases Intervals.icu uses making a lot of the activity stream, segment and interval data inaccessible for a while.
