To start with in set up you have to select the correct device type before the app can find it. If you have an ASUS ZenWiFi AX and incorrectly select AX Hybrid or Mini it will not show up. Since the app can obviously work with any of their products why not just search for any of them? Not a huge deal but it added a few minutes of frustration when I initially got it wrong. Then, if you’re setting up multiple devices you have to either turn them on one at a time or guess as to which is which. Again, more of an annoyance than a deal breaker. Next, it apparently can’t tell the difference between an iPad and an iPhone so it is nearly impossible to figure out how to name them. If you disable one temporarily to identify which is which you can’t re-enable it from the same place. You have to navigate to a different menu to do that. Why?In trying to set up and name my devices one of them got entered twice and there’s no way to remove the duplicate entry.I have three different passwords - one for the network, one for an ASUS account in the app, and a third for an ASUS account when I tried to register the routers. Again, why? BTW, I have so far been unsuccessful in registering my routers since after entering the SN I get a pop up that says successful but the underlying page says “Server busy, try again later”. That’s just the first hour’s worth of frustrations.
