Activity not showing up

Did a ride today and it isn’t showing up. I also tried uploading the .fit file (downloaded from intervals.icu) and got an E-Mail that it is done but that didn’t work either:

Your bulk upload of i57531765.fit is now complete.

  • 0 files processed
  • 0 files imported

Mind you I have just come back from vacation and I did the trial version before it and everything worked fine.

Any way to troubleshoot what’s going on?

Edit: So the upload has to be .zip (which it says but I didn’t read the first time round) so at least manual upload seems to work.
