We are currently updating the OP Help Center content for the release of OP 14.19 or OP 19. OP 19 is a member of the certified OP 14 family of products (official version is 14.19.1), which you may see in your software (such as in Help > About) and in the Help Center tabs labeled 14.19. You may also notice that the version number in content and videos may not match the version of your software, and some procedural content may not match the workflow in your software. We appreciate your patience and understanding as we make these enhancements.

Why can't OP just put something on the notification sidebar?

We will update the notification sidebar.  However, sometimes the technology issue is related to being able to access/log on to OP.  Also if a user is already logged into OP, s/he will not see the alert on the notification sidebar.  Text alerts provides another communication channel.
