Happened to me, online rejection. When I went in person after the rejection they accepted it with no problem. They notified me online of the reason for rejection, needed to update my TM30 as I had a new passport.
Seems the online links to the TM47 and TM30 database but in person they didn't. All working now though.
Thanks, didn't think it would. Will inform them and will also ask for the online TM30 login info so in the future I can do it myself. Passport and address are correct. :-)
