Trailforks doesn’t have any trails for certain countries

Edge 1050. Trailforks found the local trails in my small hometown in the UK, however when I’m in Chaing Mai, Thailand, where there are multiple Trailforks networks, I get no results when using Trailforks MTB navigation.

This is really frustrating as it would be a great feature to use to figure out connecting trails without pre planning exact routes etc. 

I have the correct maps for Thailand loaded, there only appears to be a single global Trailforks map available anyway. Road maps are fine. 

I was running the latest release firmware adjust upgraded to the beta, but this still doesn’t work  

Any ideas?
