When switching to a paid account / when the meeting creation host does not participate

Two questions

Two question

(1) About meetings created during free account.

For example
Today: Create tomorrow's "A Meeting" with a free account
Tomorrow: change to a paid account. Can the "A meeting" created yesterday continue for more than 40 minutes?

(2) If the host who created the meeting does not participate and only an alternate host participates, does the meeting settings (screen sharing privileges) associated with the individual account remain the same for the host who created the meeting?
