We're trying to integrated Google IMA DAI into our channel and we've come up against a hurdle with the RAF certification. The channel has passed all other tests but there's a requirement to support Nielsen DAR and Comscore VCE.
The issue seems to be that the DAR and VCE pixels are being blocked. Roku has suggested there's a config in the DAI SDK in which we can whitelist these pixel URLs and everything should work. However...it's not clear (or documented, that we can find) what this config whitelist is or where it exists. Our support at Google also is not familiar with this whitelist.
Anyone run into this before?
