The "Announcments After Mass" will be after the Prayer After Communion and NOT when the priest purifies the sacred vessels and the assembly should be praying, or worshipping and thanking God. These precious moments after Communion should be a time when as individuals and as an assembly we become even more the Body of Christ with Christ as our Head. In fact, the directives for "announcments" at Mass call for this and that the announcements not be too long nor too many.
