Hi @margaritabelt12! To make the change to a plan with fewer members you will first need to cancel the current family plan and then re-subscribe to the lower tiered option, and re-invite the family members. Please let me know if you run into any issues or have any other questions. Cheers!
I asked around and it looks like that yes, you will have to wait until your current plan runs out before you'll be able to enroll into the you + 2 option. If I hear anything different I'll make sure to let you know, and please let me know if there's anything else.
