Need Meta Business Suite / Facebook Page Access Expert to Resolve Business Portfolio Lockout

I need help resolving a Meta Business Suite access issue for my company. I created/connected a Facebook Page through Meta Business Suite using my business Instagram account. I can still access the Instagram account and I can see the business/Page inside Meta Business Suite, but I am blocked from accessing settings or making administrative changes. Meta appears to be treating this as an account verification or access issue, but standard login, email, and 2FA troubleshooting has not resolved it. I need someone who has direct experience with: Meta Business Suite Facebook Page access and full-control permissions Business Portfolio / Business Manager ownership issues Instagram-to-Facebook Page connection problems Meta support escalation or Page Admin Dispute processes The goal is to diagnose exactly what happened, help me recover full administrative control, and guide me through the correct Meta support/escalation path if needed. Important: I am not looking for generic social media management. I need someone who understands Meta account access, Business Suite permissions, and recovery workflows. What I need help with: Review the current Meta Business Suite / Instagram / Facebook Page setup with me over screen share. Identify whether the issue is Page access, Business Portfolio ownership, full-control permissions, or account verification. Help me avoid making the problem worse by disconnecting or duplicating assets incorrectly. Prepare or guide the correct support request to Meta if manual review is required. Stay with the issue until we have a clear recovery path. Ideal candidate: Has resolved Meta Business Suite lockouts or Page access issues before. Understands the difference between Facebook Page access, Business Portfolio access, and Instagram account access. Can explain the issue clearly and guide me step by step.
