After I completed uploading all my documents and my wife's documents(through attach button for each applicant where different documents are asked), I was getting that message when I tried to upload my child's documents.
Later, I have tried using the Attach button on the top right corner and selected my child in the drop down menu but still I am getting the error.
Please suggest if there is a way to upload my child's documents
I always used the Attach button on the top right corner and there in the drop down selected each applicant's name (me, my hubby and kid). As I have uploaded so many of my docs I have got this error in my name. immediately with other names I was able to upload. So my remaining 2 docs of employment I uploaded in my hubby's name mentioning in the description that "Unable to upload on XXXX name".
So this will be a work around for you to upload kid's docs by using the top right corner attach button take your's or your wife's name and mention in the description that unable to attach for kid.
Another interesting part is yesterday I wanted to upload my PCC, just like a chance I have again tried my name and unexpectedly it got uploaded on my name too without giving this error. Hence, I have uploaded again my other two docs of employment on my name which were uploaded on my hubby's name earlier.
Hence my suggestion is first upload kids docs on your name as CO looks at all the documents and keep trying to upload on kids name if you are very specific.
Hope this helps.
