Hi rodhx, Thank you for your honest feedback about upgrading to Check-Ins 3.0. Would you mind emailing our support team about the update and the struggle you are having. We know how frustrating things can be when systems are not working and you have multiple families waiting in line. We don't want that experience for anyone. If your up for it, we would love to work with you to get your situation resolved. The email address is: support@planningcenter.com You can also click the "?" in the tool bar on the right side of your Check-Ins admin screen.
