I noticed when I change banners on my پروفائل page, the old ones are saved. Is there a to how many آپ can save and can I خارج banners once they're saved?

So far I don't find any of how many banners آپ can save. And آپ can't خارج any of banners آپ save here.

The reason آپ can't خارج banners (or backgrounds) is probably because you've spent سونا buying them in the first place. If آپ deleted them, آپ wouldn't have what آپ spent the سونا for any more. They might make it possible to خارج these things in exchange for returning the سونا in future.
