On Android where you click top-left (your own profile image) and then when you’re on the list of accounts and pots there is a pen icon top-right which, when pressed, allows you to mark a pot as hidden, or re-arrange the order. There is no “hide” button.
If you have hidden the pot then you won’t see it in the main list until you un-hide it.
This is standard functionality in the app although it’s possible there is a variance in the way different operating systems handle it.
Yeah it’s odd it had other interactions on there alongside the hide option, which is weird as an actual pot doesn’t have one located there.
Perhaps you’re right and it was just a new elaborate advert for pots, it would explain while I’m not able to see it even if I go to the pots screen in my profile.
