I usually export my activities in TCX format, but today exporting from Garmin Connect Web to GPX or TCX isn't working because the activity is longer (e.g., a 4-hour run). There seems to be an error or timeout, but there's no notification. It worked a few weeks ago, but not today. Please fix this. I'm really disappointed. If this continues, I'm leaving Garmin...
Added July 20: After a few days and several attempts to download the TCX file, it finally worked somehow.
