We had found that a number of users were copying names from a spreadsheet which included a comma within the name. For example - "Smith, John"
By using a symbol in a child's name it was causing the speech engine not to load and thus, no dictation. The error has been corrected and names can no longer be inputted using symbols.
If you have any children with names containing symbols, it is suggested that you edit them on the "Children" page of Mark Mate and remove any symbols from their names.
