When editing the schedule in the new admin portal at admin.goto.com, any changes made to the schedule are saved instantly. This is not the case when using the old admin portal at onjive.com.
I think it's definitely a usability problem if any update, especially erroneous ones, are instantly saved. You can imagine the unintended consequences if all calls start to follow the "when closed" route when the business is supposed to be taken calls, and conversely, if calls start to follow the "when open" route when the business is actually closed.
This is why I still use onjive.com to edit the schedule, but I understand at some point, onjive.com will be retired. And even still, customers are being steered to admin.goto.com and are sometimes making unintended changes to the schedule.
