bitmovinAdTagLoading
When enabled, the player itself downloads the initial ad tag. For ads with AdSourceType.Ima, this means that the provided ad tag is not fetched by IMA. If the downloaded ad tag is a VMAP, the VMAP structure is processed by Bitmovin Advertising and any resulting VAST responses and wrapper are handled according to the configured AdSourceType. This property only has effect on ads with AdSourceType.Ima.
