Sync problems with Connect with Express 7.28

Hi,

since the last update to Garmin Express 7.28, Express no longer syncs properly with Garmin Connect. Express reports that the sync is completed, but the activities are not uploaded to Connect. In Garmin Connect the last successful sync is still shown as March 3rd (before the update).

If I try to upload the .tcx files manually, they are rejected with the message:
"An error occurred with your upload. Please try again."

I have not changed anything on the device (EDGE 705) since the last workout that uploaded correctly on March 3rd.

Things I already tried:

Reinstalling Garmin Express
Removing and adding the device again

Does anyone have a hint what might be causing this?

Thanks for your help.

there is something interesting in this as my old 410 stopped syncing the very same date, I think I was using v 7.24 but this smacks of something internal to express and or Garmin.

Quick question, when you go to Garmin connect and check the specific device does it show a last synced date of March 3rd, even though no doubt you have apparently correctly synced through GE several times since?

Yes, it says "Synced Tuesday, 3 Mar at 16:10"...

Ok this definitely seems like a local garmin Exp issue, two separate devices with no connection showing issues after the same date.

Can you upload to the watch, that still works for me?
