Hi Masu.
Thank you for posting on the forum.
With regard to the issue you are having, do all of your iPads have the same name?
Please could you try and update to ActivInspire 2.0, which can be downloaded from the Promethean Planet website.
Also, please update your ActivManager/Driver version, this can be downloaded from article 10902 on www.PrometheanKB.com.
Please try and also restart your ActivEngage 2 server. You can log in to your admin account on the ActivEngage 2 page, and restart the server from the 'Configuration' page. Please also reset your hub from the ActivManager Control Panel under the 'Hardware' tab.
If the issue persists, please contact Promethean Technical Support for further advise.
You can contact us by phone or by filling out a contact form. Please quote the reference number which I have created for yourself to help resolve this issue. Your reference number is: 00430080.
