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.
