@brett-monday.com - Ya, after some looking around, the things this person expresses in this post:
Are accurate, and my current challenge is described as “monday offers a very limited view of linked/mirrored relationships. The only way to see a linked relationship is to be on the linked board . If you are on the parent board, there’s no way to see an overview of the links.”
This makes managing tasks that roll up to a project from the project board impossible and Monday.com not really realistic to manage agile projects of any complexity. I hope you guys plan to fix this, else my search for an good product continues…
