What are some of the showstoppers that are preventing you to use Zoho Showtime?

We are considering using Showtime and are looking to learn from others on this community.

What are the biggest issues/challenges/show-stoppers that you have come across when using Showtime that we should be aware of?

e.g. I see one big one for us - Zoho Showtime sends a link when an attendee registers for the event, and this join link can be used by attendees to join a specific course that they have paid for. However if they accidentally delete that email then there is no way to regenerate that email/link and help them.
