I just saw two seemingly related instances where a popup opened and closed automatically about 5 times. The first instance was viewing a tree that was previously on the pro plan; the “Locked” popup opened and closed many times before finally staying open. The second instance was when creating a new tree and seeing the “Unlocked” popup which opened and closed many times before remaining open.
Also, perhaps it’s not intended for the “Unlocked” popup to show when creating a new tree.
