Slow email loading on Wi-Fi, not cellular.
I’ve had an issue since updating to iOS 15.6.1 with some (certain types of graphics) of my email taking forever to load on both my iPhone 8 and my IPad However, it loads quickly when I use my cellular data and disconnect from wifi. My wifi works perfectly on my iPhone otherwise. I’ve reset my internet router, done all the iPhone resets and reinstalling mail the app with no improvement.
