Friendly reminder to please use the drop down menu to identify and describe when uploading documents to your listings. If the document you are adding to the listing is not there then you may type in a description.
In the example above you can see that the document is identified as PLAT, however, this document name was not chosen from the drop down menu so Flex did not recognize that a plat was uploaded and sent this listing into the "Unapproved" abyss. Also, anytime that you make a change to a listing and save it if there is not a Plat identified in the documents it will kick the listing into the unapproved status as well.
Below are instructions on locating, saving, and uploading a plat to Flex.
