Whenever I connect the device to the internet or try to install any app on my device, I have been getting the Asus Router App Connection Failed error message. What shall I do to get rid of these error messages?
Cannot install the app
What’s your device? If you can’t install an app on your iPhone, then you could first try to force restart your iPhone to fix your issue well. Of course, using iTunes or any other ios repair tools such as TunesKit iOS System Recovery is also worth being tried. Or you could directly ask the official help.
