Cannot load to Garmin Connect

Hi Guys
Great app, but its stopped working 'properly' in the last few days. I can no longer load my workouts to Garmin Connect. I think they load, as they are automatically transferred to Training Peaks but they are not shown in my activities in Garmin Connect. I have reinstalled the app twice, to no avail.
Is it their website or the app?
Help, please
John

I have just experimented with files from the Wahoo app as well. I am aware that the Imobile app hasn't be updating Garmin Connect directly, so I have been uploading the tcx files from drop box, and it has worked - until last week. The same thing has happened with files generated by the wahoo app. However, my Training Peaks account is linked to Garmin Connect, and the files seem to get picked up in TP from Garmin Connect. I think that Garmin are being cheeky by not displaying any files not generated by a Garmin device (but they are in the GC account! Am I correct?
Cheers
John

PS 19/03/17 - I can confirm this now since the files upload to Strava fine. Nothing wrong with the files it is Garmin.

Update 30/03/17 - I've been following on the Garmin forum, where it was reported. Garmin admitted it was there problem - and it has not been fixed!
