Hello. I've had the Github power-up working on Trello, but this morning it is no longer working. It appears in the menu bar, is enabled and linked to the relevant repo.
I've tried reinstalling it, clearing my browser cache and cookies and using a different browser - all with the same result.
Existing cards that had links to Github pull requests still show them, but I cannot add links on any new cards.
Any suggestions, as I'm very new to this!
