You should check for “is true” or “is not true”. Or, in the new version, “is checked” or “is not checked”. “Is not true”/“Is not checked” will cover both false and empty. ---

There is however a difference between false and not checked, in that not checked covers both the false and empty states. Whereas false does not cover the empty state. The important thing to be aware of is that Glide booleans have 3 possible states: true false empty, or null The default state for a boolean when it is first created will be empty, and it will return to empty if you clear it with a set column values action… ---

Thank you guys @ThinhDinh and @Darren_Murphy ! I learned something today ! Always use “is true” or “is not true”. ---
