LINE for Windows Phone 10 lag?

[zkyevolved]

Hello everyone! I am wondering if anyone with Windows Phone 10 uses LINE (by Naver) to chat? I used it on my Lumias and it was SO SLOW to download new messages. This was due to Line closing the connection and then having to renegotiate with Naver's servers. Can anyone on WP10 confirm that Multitasking as been improved to not close the connection and NOT take forever to download new messages!?

Thanks
