My Account - Notification Log

Great product! Communicates perfectly with my cellphone and accepts commands from within my Avast Mobile Account. Only problem so far is that I can’t delete the activity notification log within my account for my cellphone, which I access via the Avast website using my computer. Tried deleting by selecting one at a time or selecting delete all, but it just won’t do the delete action when I select the button and confirm the action. Any ideas would be appreciated. Thank you.
