Mashable: Some users have reported that messages sent as direct messages (DMs) on Instagram or through Facebook Messenger are disappearing as soon as they are sent.

Since last evening, Instagram and Facebook Messenger have been experiencing troubles, with numerous users taking to social media to express their dissatisfaction with their inability to communicate using these Meta-owned services.

Some users have reported that messages sent as direct messages (DMs) on Instagram or through Facebook Messenger are disappearing as soon as they are sent. The problem has not been resolved as of the time this report was written.

However, this is merely a partial outage. Everything else on the app, at the very least for Instagram, seems to be running smoothly with no additional issues reported.

There is no idea when this issue will be rectified because Meta hasn't issued any public notification about it.
