Why are all my messages getting auto archived? I have One Plus 3 running OxygenOS (Android 6.0.1). Of late I am facing a weird issue. All my important incoming messages (SMS) are automatically moving to Archived section. Also I am getting no notification for them same. Only few crap SMSs which I don't care about land up in Inbox.

How to fix this? I am missing on important updates because of this. I am using the default Messenger app.
The issue got fixed for me. I went to Messenger app's App Info page. From options (top right corner three vertical dots) choose Uninstall Updates. My app already started working fine after this. However, it was again auto-updated to latest version and is still working fine.
