I mean there is an issue with new 06-2017 version of imm5669, once you validate, a small little window on top right corner shows status of validation will flash yes under which means it is validated.
than you save it and when you save it and open again same status is no, and yes thats my point if it was not validated it shaouldn't have been uploaded as per cic letter.
And yes they have not asked the digital photo from us. I think the photo specs were changed as i submitted bigger photos for her and not as they used to be so may be if someone sent wrong photos or they were not able to scan them clearly, only from those applicant are being requested for pics.
