Sluggishness in IOS 13 Mail App

Forum
iOS & iPadOS

In IOS 13, I occasionally encounter a lot of sluggishness upon opening the mail app and just after exiting the app. Does anyone know if this is a IOS issue or something specific to Voice Over? I don't suppose it really matters, as the impact is the same for me either way, but I'm just curious. It could be that IOS 13 pushes the capabilities of my iPhone 6s but I don't have this problem in any other app.
