After the inquiry of Canadian immigration progress, there has been no result, and it has not been said that it is under review. The following explanation will appear every time. What does this mean?

This online progress query is useless. The only update is that after your case is filed, it will show the receipt. It's still being processed. The information on this web page you posted here is to tell you that the information you provided can't be found in your case now. Maybe your file number is wrong or it hasn't been filed yet. When did you submit your application? If it is submitted recently, don't worry. If it has been a few months to a year, you can go up and have a look. But don't get your hopes up. Waiting is the only way.
