Emails on apple mail app taking ages to load

I’ve also had this same issue since updating to iOS 15.4.1 with my mail taking forever (sometimes not loading at all) on my iPhone XR. However, it fully resolves when I use my cellular data and disconnect from wifi. My wifi works perfectly on my iPhone otherwise (can stream videos, browse internet, etc). I’ve reset my internet router, done all the iPhone resets and uninstalling/reinstalling mail apps with no improvement whatsoever. I don’t want to depend on cellular data every time I need to check my mail when my wifi works fine outside of the mail app.

Hey clairefrompotters bar,

We'll be happy to help out with this issue regarding Mail taking a long time to load.

Have you tried switching networks? This can rule out the issue being with the connection. For example, if you're connected to cellular data, try switching off cellular data and connecting to Wi-Fi only, or vice versa. If you're not sure how to turn off cellular data to connect to Wi-Fi only, follow these steps: Use cellular data on your iPhone or iPad - Apple Support.

Keep us updated!

clairefrompotters bar,

Thanks for trying that. Have you restarted all devices? You may even want to try restarting your router.

If at all possible, to further isolate the issue, can you test on another Wi-Fi network?

Let us know what happens.

Have a fantastic day!
