I’ve been moving items between lists with New Clear for months now with no issues, but one of the latest builds introduced a bug. If I want to move something, I grab the item/items, and pinch the list closed, but instead of seeing my lists, I’m taken to the top level. If I can manage to get it to the list where I intend to drop it (which isn’t easy, because it sometimes seems to have a mind of its own as to where I land), the app freezes and requires a quit and re-open in order for me to use it again.
I’ve wanted to move items between lists for like forever but could not come up with a way to do it. Never occurred to me to use two hands.
Be that as it may, I have been able to move items between lists without any trouble like you describe. Will pay attention if I am able to reproduce.
