Intelliboard will take a long time to"open up" or start for the following reasons:
You are enrolled as Editing Lecturer in a very large number of LEO units
Your might have remained enrolled in your LEO units (including archived units) indefinitely. Although this may give you continued access to past units (including ones you no longer wish to access), Intelliboard will include data from those units while it is preparing to start for your account. To help speed up Intelliboard for yourself, you may contact LEO Support with a list of units you no longer wish to access, and ask them to unenroll you from these.
You are an Editing Lecturer in several very large units - e.g., with hundreds of resources or activities, and over a thousand students.
National (multi-cohort) units will cause Intelliboard to take much longer to launch, and for any report within those types of units to be processed. In future, it may be best to run these as campus-based, single cohort LEO units.
LEO units with many "orphan" resources and activities. These resources and activities may have been added in past versions of the unit but kept hidden and not deleted in successive study periods, when teaching staff do their "rollovers". A clean up of these resources and activities will speed up Intelliboard's reports for these LEO units.
PLEASE NOTE: Even if Intelliboard takes a long time to start for you, it will still work. Once you can see the Intelliboard in LEO, the rest will work, with small reports quick to display and larger reports taking longer.
