Not getting messages – Messenger Review

I keep getting notifications that I received a new message but when I open messenger there’s nothing there. The notification icon is lit up with the number of unread messages but the messages aren’t there for me to open and read or respond. Please fix ASAP I run a business on Facebook and use messenger for my clients to contact me but they can’t reach me because the messages aren’t there when I open the app
