Problems using URL shortener with document links

Aug 6, 2013 at 7:07 PM
We have been using URL shortener for quite a while. Thanks you for a great product. But recently the users have noticed a problem. If you open a document in an SP document library using a shortened url you cannot edit the document. The "edit document" button and yellow bar never shows up. If you try to edit it anyway it tells you the document is read only and cannot be updated. If you access the document using the standard link then the edits work without any problems.

Any ideas on what may be happening?
