Can't enable webinar email ICS calendar attachments

[AKNPS_pres]

Hello, I have a Pro account. I have full admin privileges. The instructions for enabling ICS calendar attachments are not working for me; I do not have an option to "Send ICS calendar attachment along with webinar invitation/reminder." Does anyone know why this might be happening? https://support.zoom.us/hc/en-us/articles/12546370693389-Enabling-webinar-email-ICS-calendar-attachm...

If it continues to be a problem you could send an ICS calendar invite from your email client. Alternatively there is a marketplace app, Salepager, that lets you send ICS calendar invites to registrants with their unique link.
