I used this feature all the time, loved it. If I had a label called "Project" for example, I was able to type #project as I was typing the text of the new card, and the label would be added for me ... or at least suggested that I could press enter to add.
This feature recently stopped working for me.
I've not changed my plug-ins, power-ups or extensions. I'm using Chrome.
I really miss this feature as a quick way of organizing my new cards.
Any thoughts on why this stopped working?
