Ability to choose which identity to keep when going back to a free plan.
Please add the feature to allow paid users to decide which identity they get to keep if they return to the free plan.
I signed up with a protonmail.ch address but found myself mostly giving people my protonmail.com address. I want to go back to a free plan now but not being able to change my primary identity to the .com address is a problem.
Yes this is a must have!
