If you are encountering the following message :

That means Meta asks you to confirm the connection between the page and your IG profile. 

Please follow the next steps from the FaceBook web platform (not the app): 

CLICK on your FB profile picture in the up-right corner --> SWITCH to your relevant page --> Settings & privacy --> Settings --> SCROLL down in the sidebar until you see "Connected accounts" under "Permissions" --> CLICK on IG --> and Confirm your connection by entering your login details to your IG's account.

After that, close and open the IG app again. Check your Edit profile section again to see if the orange "Confirm" message is gone.
If it does, try again to link your IG to the Humanz app :) 

another way is:

Enter Meta business suite



Follow the Get Started button.
