What I need is a TCX log file.
However, since recently you can no longer download TCX or GPX files.
This problem occurs when downloading files larger than 10 MB.
All time and in all browsers, the error message 'Uncaught (in promise) -> status: 504' appears repeatedly.
We suspect an issue with the connect.garmin.com website server.
There is no way for the user to resolve this directly.
