In the past, I have been able to set the preview location to my IP address and then Run the project, type in "(ip):(port#)" on the iPhone, and would be able to preview game on iOS. Now, this doesn't seem to work. Does Construct 2 not do this anymore, or is it maybe a flaw in the iPhone?
Also, Construct 2 lists my IP address as 10.0.0.10, which doesn't seem right (that means private network, right?). Don't most IP addresses start with 192.168...?
