I try to insert email template in email in lightning experience but get internal error when modal window "Insert Email Template" opens. On classic everything works fine. It seems something related to permissions because some other users can insert email templates without any errors but I have no idea what I need to add. (Error Id: 1684250086-84181 (-412177269)) enter image description here

  • (a) you'll want to contact support, and (b) it would be useful if you'd edit in the error number in as plain text so we can look in to it.
