The info bar sits at the top of your inbox and notifies you of important information about your account or your current settings. It also displays your Sideline number and allows you to copy it so you can share it with others.
The 1st screenshot shows a gray info bar that displays your Sideline number.
The 2nd shows a yellow info bar notifying you that Sideline needs Contact permissions enabled so we can correctly display your Caller ID.
If you have accidentally clicked the "x" and would like the info bar to reappear, try logging out and logging back in for it to reset.
If you have any further questions, please submit a request.
