I don't use messenger mainly because my RAM is 1GB and I hate how bloated it makes my phone feel. When I did use it however, I experienced it. Possibly because of the RAM yet again.
All the time. Whenever I open it on my low-end Lumia 625 running windows 10. I uninstalled it. This is actually because Messenger, Facebook, Instagram and a lot of other apps have been ported from the iOS ecosystem. They are actually not very stable on Windows, and you need high enough specifications to use them without crashes.
