My webinars are not 1 hour long. They vary between 30-45 minutes. It's painful to schedule the series because the interface cannot hold onto any increments other than 1 hour. If I have an event that's 1-1:30 one day, I add the next session but want it at 2PM, the end time jumps to 3:30. It's been like this for years & I would have thought GoTo would have figured this out & fixed it by now.
