Honestly, I'm not familiar with the issue, but I'd be looking for the differences in the version of iOS and FMGo on the iPads and seeing if there is a difference.
I would also be tempted to avoid using the "[" and "]", since these are normally used in the "[Full Access]" and other FM reserved levels of access.
I'll check they are all up-to-date. Maybe it would be worth hard-rebooting them all? as mon-fri they are in use all day and never get restarted.
I see, I just kept it the same as the other access levels but i'll update them accordingly thanks.
