This looks like a server-side issue. I have escalated to them.
Thank you. Let’s keep in touch, please! 
Hi Justin,
I was curious to know if you get any news for this problem?
Thank you.

Hi Justin,
I tried using CyberTracker again on the phone where I previously reported the upload issue. You mentioned it seemed to be a server-side problem. I’m not sure what changed on your end, but it seems to be working now—I was able to upload the data successfully. Just wanted to let you know that the problem appears to be fixed.
Best regards,
Gwen
Thanks Gwen, appreciate the follow up!
