VPAID <MediaFile> detected: VPAID is deprecated by IAB Tech Lab

WarningDetectionIAB VPAID 2.0 (deprecated), IAB Tech Lab Deprecation Notice 2019

A element with was found. The IAB Tech Lab officially deprecated VPAID in favour of SIMID (for interactivity) and OMID (for verification). Most CTV platforms including Roku, Apple TV, and Fire TV block VPAID outright. Serving VPAID to these environments results in a blank ad slot with no error. Desktop browsers still run VPAID, but this will narrow over time.

Why this matters in production

Treat this as a migration and compatibility warning. VPAID issues often survive desktop QA and then fail silently on mobile, CTV, or SSAI paths. Detection rules tell you that legacy VPAID is still present in the tag. That matters because many modern playback stacks block VPAID before the creative ever starts.

How to fix

Migrate interactive creatives to SIMID 1.2 (<InteractiveCreativeFile type="text/html" apiFramework="SIMID">). Migrate verification scripts to OMID (<AdVerifications>). Keep a standard <MediaFile> MP4 alongside any interactive layer as a fallback.
