Thank you for the reply.
Unfortunately I've tried all that. I even did a secure erase of my BB9930 and installed a backup from a year ago when everything was working fine. All software on the 9930 is up to date. Plenty of available memory also. Not sure why I'm not getting instant Twitter DMs. Twitter on my iPad gets the DMs the second they are sent just like my 9930 used to. I'm stumped.
