Scheduled blocks should not be editable

I would like to report a loophole in Strict Mode.

Currently, if a blocked hour has not started yet, it can still be disabled shortly beforehand. For example, at 11:55 AM I can turn off the 12 PM to 1 PM block and then use all previously blocked apps during that hour.

This defeats the purpose of Strict Mode, since it allows users to bypass restrictions right before they take effect.

I think upcoming blocked hours should be locked while Strict Mode is enabled, so they cannot be modified or removed at the last minute.
