The new version has separate dialog boxes for the "Time is up" and "Extend Time" messages. So, I cannot extend my child's time, because I have only seconds to enter my e-mail address, my password, and select an extension time before it shows the "Time is up" message and kicks me off. For now, as a workaround, I have changed my childern's house rules from "Block ... from using this device" to "Report the activity, but let ... continue using the device".
Please fix this bug immediately.
