Litter Robot 4 will incorrectly report that it's full sometimes
Yesterday my Litter Robot 4 reported it was ~35% full and this morning it said it was 100% full. I forced a cycle (remotely as I'm not at home) and it now says it's 44% full. I last emptied the drawer 4 days ago and the cat fills the drawer after 7-8 days of use, so I know the 44% must be accurate.
Any idea why this is happening or how I can prevent it?
