Added cards to a board keep disappearing

[Osinachi Anokwute]

Whenever I try to add a card to a board that I am a member of, it keeps disappearing. My fellow team members have complained of same thing in their boards too. All of this started on the 20th of May, 2024.

Do you see any banners on that board with messaging about it being in read-only mode?

It sounds like the Workspace may be over the free collaborator limit. Free Workspaces in Trello are limited to 10 collaborators (including both Workspace members and Workspace guests). As of May 20, any boards in free Workspaces over that limit are read-only.

If that's the case, a Workspace admin will need to either remove collaborators or upgrade the Workspace.

You can read more about the limit here: https://support.atlassian.com/trello/docs/workspace-user-limit/

@Osinachi Anokwute just to rule it out, but do you have any filters on the board? 

If not, can you try searching for one of the cards that has disappeared? https://trello.com/search

If you're able to find that card, do you see anything in the activity that might explain why it has disappeared? E.g. it archived, got moved somewhere else.
