 * Hi [@christopherzenmon](https://wordpress.org/support/users/christopherzenmon/),
 * Hope you are doing good.
 * Can you please then Settings > Account tab screenshot? you can hide the user 
   and pass the screen.
 * Also, share the Diagnostic test report and explain the use of the case of this
   issue then I can test it on my staging websites.
 * Thanks
