Our support bay took quite a battering over this, it looks like it is now resolved.
We have now resolved the issue with recall forms dated 23/4/12. As mentioned this morning any forms already submitted that were rejected we will reprocess using the original files stored in our DB. There is no need to any agents to resend.
Please note as part of the reprocessing file some agents may get a file note from the XIT Client saying that the supplementary return they sent is a duplicate. We will be advising agents to ignore that message for this form and instance.
If you have any question please call me.
