Trello custom fields is a power-up that allows Trello users to create text, number and other types of fields with tailored values.
Although Placker provides custom attributes as one of its features, it is also compatible with Trello custom fields and usually they are integrated seamlessly.
However, in case it happens that values in a custom field are not reflected in the board or in a mirrored card, you can click the board title to open its settings, access the attributes tab, edit custom attributes and click the "Synchronize Trello Custom Fields" button, as in the GIF below:
In case doing this and refreshing your boards doesn't work, please send us a message in the chat.
