Norton Family SMS monitoring notification blocking actual message

Since installing Norton Family on my child's ASUS ZENFONE 3, it has been nothing but problems.  First the app uninstalled all on its own, then whenever she gets a text message SMS or MMS, she gets the message "a message has been shared with your parents", but can't actually see the message!  I could (until this morning) log onto NFP and read the message and describe the picture to her, however this morning all of a sudden her device doesn't even show on my log in....BUT her device is still notifying her of messages being monitored.  I am so frustrated with this product.  It has been nothing but problems since we installed it.  I won't even go into the fact that on the computer device it is NOT filtering content like it's supposed to.  However, one problem at a time....I need her to be able to get her SMS!!!!  I've been waiting to chat with support for 40 minutes...how can we get support for this product?????
