Garmin Connect not importing TCX files anymore.

Tried several times importing a TCX file and always get the message "An error occurred with your upload. Please try again." It used to work just a day ago.

Same experience starting yesterday 3/5/26 attempting to import a TCX file. Will not load using either up to date Firefox or Google Chrome browsers. Clearing browser history, cookies, etc has no effect. I can import the file to Strava without issue. I can view the TCX file with a TCX file viewer without errors. The TCX file was created with the MSeries app that communicates with my Keiser MSeries trainer. I had the same issue 5 or 6 months ago and it magically started working again a number of days later. To me, this is pointing to a possible Garmin Connect bug as a result of a recent update.
