The 8.1 app was the best method I ever used to receive emails. It was the best egasm on PC since Halo PC. The 10 app on the other hand doesn't always sync read messages to the server, so I end up with read messages on the 10 app that aren't read in the browser or windows phone 8.1 app and messages that I read in the browser or WP app that aren't read in the windows 10 app. And yesterday the live tile has decided to undergo cryo stasis and forever tell me I haven't read a trio of messages I read in the app yesterday, instead of incoming messages I've yet to read. I'm pretty much used to the rest of Windows 10 now, and I haven't had the News app crash much in a while so I'd rather not go through the hassle of reinstalling Windows 8.1.
