After removing Manychat permissions from Facebook / IG and re-connecting I am still getting the error “post not found / lost connection”.

 

Old automations are still working - I cannot edit them though.

 

New automations are NOT working at all. What else can I do to fix this? Delete Manychat entirely? I’m scared I will lose all the automations I have built.

Breathe, you won't lose your automations. The flows you built live inside your ManyChat account, not on Meta, so disconnecting and reconnecting the Instagram link doesn't delete them. They just go inactive until the connection is healthy again, then they run as normal. So you can safely do a full reset without losing your work.

The "post not found / lost connection" after reconnecting is almost always a ghost connection stuck on Meta's side, and refreshing permissions inside ManyChat won't clear it. Do a full reset instead:

1. Facebook: Settings & Privacy > Settings > Business Integrations, remove ManyChat.

2. Instagram: Settings > Apps and websites, remove ManyChat-IG.

3. Make sure "Allow access to messages" is ON in your IG settings.

4. On your Facebook Page, check the handover protocol / advanced messaging settings and make sure ManyChat is set as the primary receiver. This is usually the exact reason old automations still run but you can't edit them and new ones don't fire.

5. Clear your browser cache, then reconnect from ManyChat, and don't uncheck any permission boxes on the Meta screen. Unchecking even one breaks it.

Since a couple of you are hitting this at the same time, it may also be a Meta-side sync glitch. If the full reset doesn't fix it, that's the point where only ManyChat support can reset it on their backend.
