CANT FIND REFRESH PERMISSIONS BUTTON

Podrías pasarme el contacto de soporte técnico, es que tengo problemas también y no se por donde escribirles 

@Valentina Gatica support@manychat.com or support.manychat.com

@home_is_my_happyplace If you click the 'Help' on the bottom left you should see 'Refresh Permissions'

If it’s not there, try going to Settings > Pick the Channel (Instagram, Facebook, etc) and on the channel page there should be a Refresh option.

If you still don’t see it, it may be that you are not an Admin on the page and cannot perform this action.

If none of these work, you’ll need to get support to help you.

it’s not there!

It’s not under help and i only have an API settings and it’s not there either?

Then you’ll need to get help from Support unfortunately… :(
