Connectors: bring in a tool you already use — Connect an account (2)
A connector with a page on the RowFold website, its own or one it shares with similar tools, has a What it does here link on its card, which spells out the setup that a tile cannot fit. Worth following for anything involving a calendar, where connecting the account is only the first of three steps.
A tile marked Needs setup isn't broken and isn't something you can fix: it means this RowFold deployment hasn't registered an application with that vendor yet, so there's no Connect button to press.
A tile marked Unavailable is one the vendor has switched off. Its card says what happened, and it can't be connected until RowFold rebuilds it.
