Hello Gillz888,
It seems this is the new norm of IRCC. Your case makes it the fourth I have come across online. The first applicant case has been 12 days without a Confirmation of Online Application Transmission and Confirmation of Submission notification.
If you have login into your GcKey to check, and still not reflecting, and if you are sure that your payment for your application fees (including biometrics if you are a first-time applicant) was successful; raise a webform/email to the visa office handling applications from your country. Upload the printout evidence for the application fee payment. Use URGENT: Application Submission not Confirmed.
I am not sure if this will resolve the situation, but it is a proactive move that can eventually be helpful.
