Immediately after connecting your Facebook ad account to Nosto none of the campaign types are available, because Nosto first needs to sync product and audience data with Facebook. This might take from few minutes to few hours depending on how much traffic and products you have.
Demographic targeting campaign is typically available first, while all re-targeting campaigns might take a bit longer to become available. For example, if your store doesn’t have many cart abandonment events, in practice users abandoning their shopping carts, generating the re-targeting product feed will take longer, possibly multiple days.
Lookalike targeting requires a substantial amount of visitors from each country so your main countries will be available shortly, but regions where you receive only a limited amount of visits will take longer to become available for the campaign type.
