@Kmdebs your instagram should be connected with a facebook business page, create a fb page and connect it with instagram and then try to link instagram with manychat
Hi, @Kmdebs!
The settings on your screenshots mean that Manychat has permissions to connect to you IG Account, but that doesn't mean that it is connectet to your current Manychat Account. If you have any old Manychat Account (or someone connected it in the past), you won't be able to connect it again to any other account before removing it from the "old Manychat account”.
If you know someone that could have connected it before, talk to them in order to remove the IG Channel from it. After that, you will be able to connect your IG to the new Manychat Account.
And if you have no idea who could do something like this, it's possible to open a ticket to Manychat's Support Team and explain your case to them. If it's proven that the account is really yours, they are able to disconnect if from other accounts and it should work for you: How to get support from Manychat – Manychat Help
