Text message monitoring relies on an Apple feature called Text Message Forwarding. If you haven’t seen messages in a few days, there are a couple of possible causes.
First, ensure that Text Message Forwarding is on. You can check this setting on your child’s phone by opening the Settings app, then tapping Messages and Text Message Forwarding. Make sure the BrightCanary server is set to “on.”
Second, disable Messages in iCloud. This feature can delay how quickly BrightCanary is able to update messages. Follow these steps to disable Messages in iCloud.
