Hi,
in the documentation you say that when using AdCustomizers in TextAds the default value is optional.
However my TextAds always get rejected unless I add a default value.
example
{=shop.best_value:Guaranteed} price starting {=shop.date} // This one gets rejected with reason "Default Value is missing"
If I add a default value however it works
{=shop.best_value:Guaranteed} price starting {=shop.date:today} // This one works
Am I doing something wrong or is this a validation bug?
