Hello
I seem to have hit a repeat of the https://forums.garmin.com/apps-software/mobile-apps-web/f/garmin-connect-web/262002/multisport-fit-file-from-fenix-6-unable-to-upload-or-sync issue from the other week.
I'm working on writing my own FIT file parsing and handling tool to gain a better understanding of the format, and hopefully understand what's broken in these files to produce a tool that'll fix them more easily.
In the mean time, would anyone be able to repair my file? I did try and use the fit file repair tool myself, but I'm on a mac and running it on Windows in VirtualBox kept locking up for some reason.
