I don't have the sticker album anymore. It's not visible on the right side as it had been in the past. Is it normal/intended or is it a bug? I'm now at the level 48.

I still can't see the stickers album anymore when I log in and play. It had been visible to me in the past and I could win various prizes for gathering the stickers.

Sticker Album icon disappeared. It was available previously, but has been missing for some time (for a few weeks already).
