"on-demand" option does not work with "repeat" option

[paul]

"On-demand" calls are also limited when using the "repeat" option. Both options conflict with each other when these "grouped" ad calls are enforced. Basically on-demand calls are made for each ad slot as it is required, so if you group all the ad calls into one group, they no longer become "on-demand" across the ad slots.

If you want to use "repeat" in this way with a group set of ad calls, the best you can do "on-demand" wise is to use the "delayAdRequestUntilPlay" option:

"delayAdRequestUntilPlay": true.
"ads": {

...

}

And that will ensure that no ad requests are made until the user presses play, but when the ad request is made, the group request will be made for the 3 pre-rolls at once. The post-roll call will also be made however so it's really only partially "on-demand".
