Mail on iPad and iPhone loading slowly recently

iOS 15.1.1 was released for iPhone only. iPadOS 15.1 is, at the time of writing, the most recent update for iPad.

If you are experiencing performance issues after updating to iPadOS 15.1, a forced-restart is recommended - as this will often resolve many isolated issues:

• On an iPad with a Home button: Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
• On other iPad models: Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the top button. When the Apple logo appears, release the button.
