Block this Number gives error "Failed to update rules. Please try again later". Search Terms returning "No Activity Found for this type and time period".

Android App (Client 4.3.1.19), logged in as Parent Mode on Samsung S7.(SM-G930V Android v7.0).

When I go to the Activity/Messages to view the messages, I am unable to 'Block this Number'.  It gives the error "Failed to update rules. Please try again later".  I have been able to do and use this feature in the past. (screenshot included).

Also, I am not getting any results displaying in the Activity/Search Terms (screenshot included).  I confirmed and even tested via my child's Android phone where Chrome browser was being used.  I also do not see any Search Term results when logged into the Norton Family Web Portal.  We have now disabled the Chrome app on child's phone until we have a solution.

Please advise.  Thank you!
