So, right now there are a few google play app installs that are probably geo-locked that I'm trying to test to make sure that it shows up on the geos I want, but I've tried Witopia and HMA Pro and neither of them work to test it.
I've also tried switching my user agent to an S3… I'm using Chrome, is there any other reason why it's not working?
Just use a real mobile device connected through a VPN... best solution there is right now.
Your User-Agent switcher might not be working perfectly, or the link/redirect system could be filtering you based on any manner of things... OS, browser, ISP, etc.
