My Trello board’s Activity section is missing from all cards. This is for all cards on the board.

Clicking ‘Activity’ in the board menu only opens the Activity drawer, and I cannot toggle Activity back on for cards. Closing the drawer and clicking Activity again does not restore comments. This affects all cards on the board.

Hi @Christine Samblanet,

The comments and activity section has not been removed. In Trello’s new card-back design, it is collapsed and moved to the floating navigation menu at the bottom of each open card.

Open a card and select Comments and activity from that bottom menu to expand the section. The Activity option in the board menu is separate: it opens the activity history for the whole board and does not control the comments shown inside cards.

Atlassian explains the change in the new card-back documentation and shows where to open the section in Comment on a card.

That is the problem. Comments and Activity is not on any cards any longer. I can see the comments icon, but when I click on it, nothing happens. All the comments are overmovie night card shows comments.pngbottom of movie night trello card.pngactivities all on the side.png under Activites, but I can't get them on the cards again. 

Clicking ‘Activity’ in the board menu only opens the Activity drawer, and I cannot toggle Activity back on for cards. Closing the drawer and clicking Activity again does not restore comments. This affects all cards on the board.
