I'm using "mirror card" to organize myself, mirroring the cards from teams board to my on board. FYI: I only do that on cards I'm already a member, from a board I'm already a member.
Sometimes it works perfectly well, but sometimes it doesn't, it just creates a new card with the originals card link, without any information or details.
I checked the article, but it looks like I'm doing it correctly. Can you help me understand?
