I can't seem to find any way of accessing storage. I have a legendary habitat in there that I can't get access to what do I do?

Having a bug or you haven't used your storage before? I don't know if it's the same in all platforms but I have a button at the lower left corner that has picrute with 3 emojis or something. Press the button and you find the storage box among other things.

@emil thank you so much I cannot believe I never noticed it until now I feel kind of stupid

@Haka-Taka Thank you as well I've seen that there before but I never really knew what it was so I just kind of ignored it I am so silly
