Hey ​@Mathieu Tan is this happening often, or once every now and then?

If it's happening often, contact Manychat support so they can check what's going on.

Also, make sure to test it from the mobile app to see if this still happens. Instagram's Web App is full of bugs and issues with Manychat.

If it's once every now and then, I usually consider it a normal glitch and just keep monitoring other conversations to make sure it's not widespread.

Hi Gustavo,

I started to experience it since last week. I tried on mobile app and also desktop app. if I tried on mobile app, it will send out 2 x messages automatically but still functioning. Desktop app it will restart the whole application. 

I will monitor a few more days before I write to support team.
