I've had the Trello powerup for Jira working for years but now all of a sudden it no longer works. When I go through the process to re-authorize inside Trello, I get stuck in an authorization loop. So I type in the Jira URL, which then shows the connecting screen that ends with the Authorize button (again). Click that and it takes me to the dialog where I type in the URL. Hence the loop.
Did something change? I don't want to delete the powerup as it may break all existing linkages. As of now the old card links seem to be half working. There is an attachment, but no longer shows the status (e.g. green for done).
