Upgraded to 1000 attendees webinar for one month, my previous plan is annual 500 attendees webinar

Hiya Kind Zoom Community,

I need help, I recently upgraded to 1000 attendees webinar for one month, my previous plan is annual 500 attendees webinar for an event, it shows my subscription is active.

However, my webinar that I made a week ago that already have registrants still show maximum capacity is 500.

Does anyone can help me with this problem? Thank you so much.
