No TCX export for files bigger than 6MB in Garmin Connect

Hi everybody,

today I tried to export tcx files for some workouts in Garmin Connect (Web Version) and I figured out that tcx files ending up with a file size bigger than about 6MB are not converted.

Nor error message or other indication. Simply nothing happend. I tried it with different PC's and browsers. The result is the same.  

A few days before it was still possible. 6MB file size is not a super long workout but something around a 3 hours bike ride.

Does anybody out there facing the same problem?

Kind regrads
