Hello Tom,
what timeout settings are you using for the ITSMobile services?
If the devices are not losing the remote wifi connection - this might be a solution.
If the device loses the wifi connection - then only solution is to start a NEW browser session. Would recommend setting the parameter in SICF for the ITSMobile service: multiple logon check
If searching for notes, all ITSMobile notes begin with the short text "ITSMobile:"
Useful notes:
1074234 ITSmobile, check for multiple logon
1048461 ITSmobile, system login for mobile services
1980475 ITSMobile - Configuration settings regarding Logon and Logoff
Regards,
Oisin
