Card activity and notifications not showing

[Emna Jaoued]

Activity on cards only show mine and partially 

I also don't see any notification on the board

I need to know every modification done to the card by me or other members 

Please help

Hello, Emna

Welcome to the comunity

Are you a watcher on the board?

When watching a card, you’ll get notifications for…

• All comments

• Adding, changing, and upcoming due dates

• Card moves and archives

When watching a list or board…

• You’ll get the same notifications listed above, but for all cards in a list or board.

• You’ll also get notifications for all newly created cards

And at any time, you’ll get notifications when…

• You are mentioned in a comment.

• You are added to a card, board, or Workspace.

• One of your boards is closed.

• When someone makes you an admin of a board or Workspace.

• You are mentioned in a checklist item.

• You are assigned to a checklist item.

• A due date is added or changed on a checklist item you’re assigned to.

• A due date is coming up or past due for checklist items you’re assigned to.
