Meta Ads Technical Troubleshooter Needed

I need an experienced Meta Ads technical troubleshooter to diagnose and fix a Meta Ads delivery issue.

My ecommerce brand is xxx, India.

Since approximately 22 August 2026, my Meta ad account has stopped delivering ads. Campaigns, ad sets and ads show Active, but they receive ₹0 spend and 0 impressions.

This is happening across multiple campaigns, including newly created campaigns. I have approximately ₹4,200 prepaid balance, so insufficient funds are not the issue.

I have already checked:

Business Portfolio — no advertising restriction shown
Ad account — no rejected ads
Pixel — no data source issues
Website dataset — no data source issues
Conversions API — no data source issues
Shopify catalog — no asset issues
Campaign/ad set/ad status — Active

I do NOT want generic advice about targeting, creatives or ROAS. I need someone to diagnose why the ad account is not entering delivery despite active campaigns and sufficient prepaid funds.

Please investigate:

Ad-account delivery eligibility
Hidden/account-level restrictions or holds
Payment/prepaid billing status
Business Portfolio > ad account > Page > Instagram asset relationships
Campaign/ad-set/ad delivery status
Account spending limits and billing thresholds
Pixel/CAPI/dataset assignment
Any verification or identity issue that could affect advertising
Whether Meta has an internal delivery/auction issue
Meta Support escalation if necessary

I want a screen-sharing session where you inspect the account with me and identify the actual cause before making changes.

Please do not create a new Business Manager, ad account or Business Portfolio unless you can first explain why the existing account cannot be fixed.

I need a diagnosis and fix, not ongoing ad management.
