TD's online application system has been quirky ever since we started applying for their Aeroplan Visa Infinite card back in 2014 when they launched this card. Over the years, several times we had to Save the application (if possible) and then come back and try again the next day or few days later to get it pushed through.
Some of the times the application would get submitted successfully, but there would be no final conclusion, and not even a note that it is pending. In these cases we would call TD to ask them if they can see the pending application in their system, and if found then they would help to push it through. It's important to try to apply online so that you get the correct source code for this 30K/FYF offer, else it might get coded with a non-promotional 15K offer with $120/yr fee on the first statement.
If you truly cannot get the online application to work, you can try calling TD and MENTION this promotion, and if the rep is not green like their company colours, the promotional source code will be added to your phone-in application. If they cannot do this then you may be in a fight when you find you didn't get the full 30K points.
Having said all this, I believe you can get this 30K/FYF offer without going through the RewardsCanada site, and apply directly at the TD website.

If you like RewardsCanada and would like to give Patrick some kickback then apply through his signup link, where you can see the source code in the URL link (sourcecode=rePwQEjA0OI). If you apply directly through the TD website there doesn't appear to be a source code involved, or maybe their back-end tacks one on after you've completed the application successfully.
I'm surprised GCR hasn't added this card back onto their cash back site to give a little bit more $$ incentive to use their referral channel. They win, we win. Maybe tomorrow?
