Apple's mobile phone does not pop up the authentication interface when connected to wifi.

The network signal is unstable, the device itself has problems, and the authentication page is blocked.

1. Unstable network signal: the unstable network signal causes the authentication interface to pop up abnormally. Reconnect the WiFi network to ensure the signal is stable.

2. There is something wrong with the device itself: sometimes, the cache problem of the device itself prevents the authentication interface from popping up. You can clear the cache of the device to solve this problem.

3. The authentication page is blocked: some browser settings will block the pop-up window, resulting in the authentication interface not being displayed normally. You can turn off the "Block Pop-up" function in the browser settings and try to reconnect to WiFi for authentication.
