I've just put a new release of my app on the market place with new features. i've changed the screenchot provided with the app but there is no change in marketplace preview. so news features are not displayed... is there a way to fix that ?
edit : i had not understood. i understand now that the preview image is taken from the first release published. unpublish it and the preview image will be taken from the second release etc etc...it could help someone in future...
