App card is not shown on the domain approved (other cards are shown fine)


We have two different types of cards at
One is a product with large photo card shown at anything e.g. at and an app card shown at “general pages” e.g. at and at

Validator shows that everything is fine and approved in both cases, but the app card isn’t shown in the real help.
Some caching from old times when we didn’t have a card yet? Is it possible to reset such a cache somehow?
