Upgrade on already scheduled webinars

[IlariaStudio]

I've scheduled a webinar for 500 attendees.

If I upgrade to 1000 attendees will this effect to the already scheduled webinar?

Hey, @IlariaStudio when purchasing an add-on the attendee count will immediately be applied depending on your attendee count addon; in your case being 1000 attendees. However, I don't believe while in-meeting applying the license will take effect in-meeting however, it should afterward.
