Why are renamed terms not directly reflected in MetaShare?
When you either rename a term or merge a term into another term, using these instructions, the changes are not momentarily reflected in neither MetaShare's nor SharePoint's document views. The reason for this is that SharePoint, behind the scene, runs a few scheduled jobs and once these job tasks have run, the changes will be reflected in the document views. The time for these job tasks to run vary but they should normally be done within a couple of hours.
Any changes to terms are however momentarily reflected if you edit a document's metadata, where you in the document form will see the new values, but once the edit is saved and the document is shown in the document view, the old values will still be shown, till the timer jobs have done their tasks.
Changes to the terms are also reflected directly in MetaShare's document filters, if the workspace is reloaded, e.g. by pressing the F5 button on your keyboard, but when filtering on these new values, they will not reflect the changes till the timer jobs have done their tasks.
