Instagram-Facebook Linking Fix Needed

This is what AI wrote. It's not wrong. Someone that knows this can help me quickly through some process of de-linking and reconnecting my FB and Instagram. It started when Instagram posts stopped being shared to Facebook. I was told to disconnect and reconnect the link. Once disconnected, I cannot reconnect.

Is this all I want? No. I am looking for someone to work with me via screen sharing who can help me with this technical problem in the short term and future ones in the longer term. If you also know about the most strategic way to run advertising, this could be very helpful as well.

AI Description:

Meta Business Suite keeps throwing a “Linking failed” message whenever I connect my Instagram account to the correct Facebook Page. I have already walked through every step in Facebook’s Help Center—clear cache, switch accounts, remove previous connections, re-authorize in Ad Manager—yet the error persists.

I need hands-on, technical guidance that gets the two accounts properly linked so I can manage and advertise from one place. A quick screen-share or step-by-step instructions that actually work is fine; I simply want to finish the setup and launch campaigns without more dead ends.

Deliverables (acceptance criteria):
• Instagram account successfully linked to the specified Facebook Page inside Meta Business Suite / Ad Manager
• Confirmation that I can access ad creation, audience selection, and performance stats for the IG profile within the same Business Manager
• Written recap of the exact steps or settings adjusted so I can replicate or undo them if needed

If you have solved this exact “Linking failed” issue before, let’s get it wrapped up today.
