How do I get rid of the message: Something changed. Choose a new board or list to add a card.

It's above all my workspace boards, taking up space and really annoying. It wasn't there before and I'm not sure why it's there now. Can it be turned off?

Hi there! This feature designed to allow you to quickly add cards to your most-used board, and it's based on your history. This message is showing because that board isn't accessible to you at this time (perhaps its permissions changed). You can tap on the pencil icon to choose a new board that you'd like to use as your board for quickly adding cards to. 

Totally understand and appreciate your feedback about this taking up a lot of screen real estate. We're working on ways to give more control over this feature, so please stay tuned.
