I'm facing this and can't find any solution.
I have 1 entity and using 2 separate forms for partial updating some specific fields. So I'm using $form->submit() with clearMissing = false for partial update. But if I have multiple checkbox fields (it's many to many relation), form doesn't remove unchecked data (checked data is added OK).
Is there any solutions for this issue? Thanks a lot!
