I have a Hunter-Douglas Applause honeycomb blind. It is a top-down bottom-up cordless blind. It will only lower half way, and when pushed up, hangs down slightly on the left end. It is 5 years old.

SOURCE: Hunter Douglas Powerrise blinds don't go up and down smoothly

First step is to.reset the shade , if it i an older one, hold the down button for five seconds. This should reset the shade and it should go all the way back up. Also replace the batteries if it seems slow using all the same brand.
