When the ‘Mail App Not Working’, the first thing to do is make sure your iPhone is connected to Wi-Fi or Cellular Data. If your iPhone isn’t connected to the internet, emails won’t load. Open Settings and tap Wi-Fi if you’re using Wi-Fi. Make sure that the name of your Wi-Fi network has a blue check mark next to it.
Try turning off and then back on the switch next to Wi-Fi. This can sometimes fix a small problem with the connection. Open Settings and tap Cellular if you use Cellular Data. Make sure the cell phone data switch is on.
You can fix a connection problem by turning the switch off and on again. Your phone has been sitting still for hours, and you haven’t heard a single tone for incoming emails. If this isn’t normal, you might have a problem: your Android phone is probably not syncing your emails, so you aren’t getting any messages on your device.
