If you have not already submitted the document they requested from you about your spouse through the ircc webform, you should do that first in my opinion. Also just wanted to add that I probably sent them 6 webforms before being able to link my application lol, and I think it only worked after speaking to an IRCC agent.
In your case I would send another webform with the information im sharing below, this is the response they had sent to me when I sent a webform about issues linking my application:
"Please fill out the
IRCC Web form and choose
Technical difficulties located in the drop down menu under the heading Enquiry. Please also add the following information:
- Any error messages you received. To do this:
- please include screen shotsshowing the full browser window, including the website address field of the:
- page preceding the error, and
- error message.
- All the answers provided while trying to link your application. To do this:
- once on that page and after entering all your answers, provide us with screen shots.
- The personal information page of your passport."
Hope this helps!
