You're meant to download and use the app if you're on an IOS device. It works much better that way anyway. It won't run in Safari on IOS. I don't know comprehensively what you can run it on if you want to avoid the app, but I know it'll work on Puffin. I put Puffin on my phone a couple years ago when the app briefly had a fatal bug, to keep myself going until the bug was corrected. But in my experience, everything was still sized for a larger screen, whereas the app is sized for the smaller screen. Hence the app being preferable.So Mom is Chrome the only browser that Zezo will open up on with the menu button showing in iPads / iPhones? Firefox and Safari don’t show the menu tab in iOS.
