It seems that the priority value is not taken into account in the EasySocial Ads Showcase module.
Because if for example I have two adverts.
One with high priority, the other with low priority.
And that in the module I have the parameters in attachment.
Surprisingly, it is always the same ad that appears in the module.
The most recent advert.
And there are no random ads.
The advertisement with the high priority should appear more often, than the advertisement with the low priority.
Attachments can only be downloaded by logged in users
