wifi shows as connected but disappears, only using cellular data
iPhone 14 Pro Max, iOS 17.5.1
WiFi is connected and working on iPads and Mac. Shows as Connected in Settings, WiFi. Three full bars symbol show WiFi is connected at top of screen. The symbol disappears, and the phone reverts to use Cellular data. But settings still show WiFi is connected. Toggling WiFi off and
on solves this temporarily, then WiFi symbol disappears again. my iPhone stops
using my auto connected home network again and again
