If you're still experiencing issues, try logging in on another device.

Potential Causes

One possible reason is that the app is experiencing issues, suggesting something is wrong with Messenger. You may have noticed this happening continuously.
Another reason is that you've sent a lot of messages recently. This can sometimes trigger a block, even if it's only temporary.
You may have also gone against Facebook's Community Standards with your messages, which can lead to a block. If this is the case, the block is likely temporary and you can contact Facebook Messenger's customer service for advice.
