Two out of the last three rides I have done have resulted in malformed .fit files. The file sizes seem really small too (less than 1kb). I can view the most basic information in the companion app, but it is devoid of all the ride data. In addition, it didn’t upload to Strava, and manually uploading doesn’t work either. I’ve tried uploading it to ‘fitfiletools’, but with no luck. Any help would be appreciated.

.fit files are saving malformed
