I've noticed GLStracking doesn't work. The link eBay provides, once you've uploaded a tracking number as a seller, takes you to a non working link. Here's the synaxis I get from eBay (I replaced a real tracking number for "#########":
https://www.gls-us.com//deliveryinforequest.aspx?trackingnum=##########
and what a working link directly from GLS website should look like:
https://www.gls-us.com/track-and-trace?TrackingNumbers=##########
I hope this gets fixed soon...
