No special setting that I know of; it’s a semi-public building wifi (no credentials required). If there are proxies, I don’t know about them.
I’ve also tried a local public university network. Same problem. I know very little about networking, so I’m not sure what else to do or what to fiddle with.
Will try installing Android studio. I was under the impression that Expo was a plug-and-play solution on mobile, but apparently not. An internet search sent me to the XDK, which recognized my project and gave me the warning
Warning: Not using the Expo fork of react-native. See https://docs.expo.io/. So now I’m looking into that, as well as installing Genymotion. I’m not really sure how to put these pieces together.
I’m super-new to development, so this is all pretty confusing. Lots of rabbit holes to run down.
