Incredibly Buggy

Ever since I updated to the latest version the application turned into an unusable app.. I have to restart the app every time I want to see who is online because it always get stuck and doesnt refresh who is online. The last time someone was active is completely off. On the official Facebook website it will say that the x person was online 2 minutes ago and in the messenger app it will say the x person was online 6 hours ago even if I restart the app. Also it fails to send me notification for most of the messages. My phone is completely ok. I have an iPhone 6S .. please fix the app
