I am using native.showWebPopup to show web sites in my app. However, some randomly fail.
Here is an example: I try to show “http://www.gtopp.org/data/current-tags.html”, and after two redirects, it poops out. Now, I’m skipping over -999 errors, so my code isn’t stopping at that point…simply no website appears!
Help!
