Anyone here know why the animations in the Fastmail iOS app don't run in 60FPS?

I wish they would improve their iOS app. It does leave a bit to be desired.

FYI Fastmail works really well with the iOS native Mail/Calendar app if you wanted to try that out. iOS is pretty much the only platform I don't use the Fastmail app on.

I know that this is at least somewhat on their radar. Scrolling used to not be 60 FPS either, now it is.

Is it still a Webview?

Some of it feels like so.
