Why are my CTV campaigns showing 'Ad Not Found' errors even after successful upload?

Alright, AdsVolt fam, I just launched our first big push into CTV campaigns, and I was super excited about the reach potential. But honestly, the ad platform is giving me a headache that no amount of coffee can fix. We're seeing a significant chunk of 'Ad Not Found' errors for impressions, which is just baffling. The creatives were uploaded, approved, and assigned to the campaigns without a hitch. Everything looks green on the dashboard, yet it's like the system just... forgets they exist right when it's time for ad serving. It's almost comical how a platform can be so sure it has an asset one second, then completely lose track of it the next.

[ERROR] 2023-10-27T10:30:15Z - CampaignID: ABC123 - AdSlot: XYZ987 - CreativeID: DEF456 - Status: AD_NOT_FOUND - Message: Creative asset not located for serving.
[WARNING] 2023-10-27T10:30:16Z - CampaignID: ABC123 - AdSlot: XYZ987 - Fallback: Default placeholder served.

Has anyone else experienced an ad platform just completely losing track of creatives for CTV campaigns, even when everything looks perfectly fine on the dashboard? What was your workaround or the actual fix for this bizarre creative disappearing act?
