I've been asked to upload documents for the addition of my child to my application, However, in my online application, I am unable to upload these documents due to technical issues in the IRCC system. The upload option next to the document is missing or not working due to which I have not been able to upload the documents in my online application (please see screenshot). I have tried using different computers as well as cleared my caches/cookies to see if it would help but there has been no resolution to the issue. Anyone faced a similar issue, how did it resolve. Please let me know. The last date to submit the documents in my online application is 01-Oct-2021.
