No problem, that’s what we are here for, @bogdaaamn
Thanks for sending over the screenshots with further information. If you join another user’s card you become a member of that card. If that card has child cards, you also become a member of those child cards. We’ve designed it this way so that can quickly collaborate on a bunch of cards with friends etc. However this does make junking shared cards more challenging at the moment, since you have to junk and then delete every single one. We are currently in the process of developing a multi-edit functionality to make this even faster.
The Outline only contains cards with a Visibility of /Priority’. Removing a card from the Outline, just changes a card’s Visibility from ‘Priority’ to ‘Visible’ – it does not junk or delete a card. If you ever open that card again it will automatically change the visibility to ‘Priority’, so it will re-appear in the Outline. You can find out more about Visibility here.
I hope that helps, if anything else is unclear just let us know!
P.S. Since everything you’ve mentioned here is intended behaviour I’d be inclined to rename this topic to “How to remove myself from shared cards that I’ve joined” or something along those lines and move it to Community Support. Let me know if you’d be happy for me to do this
