So, in Trello, there’s actually a limitation on how many comments are displayed on a card. It’s not super common to hit that limit, but it sounds like that might be what’s happening here. If the comments are older or there are just a lot of them, they might not show up directly on the card, and it could also explain why they’re not loading properly when looking at their JSON.
To confirm if the comments still exist and access them, I’d recommend exporting the entire Workspace’s data. This way, you can get a full backup of all the boards, cards, and comments, and you’ll be able to find what you’re looking for in the export file. Here’s a guide with step-by-step instructions on how to do that: Export all boards in a Workspace.
You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
