Exported exercises fail to import to Garmin

[delize]

When running the tool to export exercise files to upload into Garmin, I end up receiving the following error:

These files look like...

EDIT:

The largest file downloaded so far - has <5000 track points and is 3 MB:

So neither of these requirements are being reached: https://support.garmin.com/en-US/?faq=Ht3ZP52Kju075uKvqTqu99

If I run the TCX files through: https://gotoes.org/strava/Combine_GPX_TCX_FIT_Files.php Then upload them to Garmin they work fine.

It seems like both the time, and GPS Coordinates are being altered. That seems to be the reoccurring thing.

I'm getting the same thing. It was working 6 weeks ago. I'm getting the same error if I download the file directly from FitBit. Looks like Garmin have changed something in their import.
