I'm having an issue in that the green chat button on the WP

Hello,

I'm having an issue in that the green chat button on the WP Admin bar doesn't work from my iPad, nor show up on my iPhone. When I click on it via the iPad, it expands to show "Status - Available" and "Friends Online" with their respective arrows on the right. However, as soon as I try clicking on either one of those, it collapses back to just the green icon. Any suggestions?

Thanks,
Michael
