the photo uploaded in the neet application form is of blue background and the date is also not mentioned .will it be a problem?

NTA ideally notifies Candumidates requesting for uploading Photograph, Signature and Thumb impression if they do not meet NTA guidelines. But since the correction window has been opened multiple times, Candidates themselves can upload correct images. The blackground colour issue might be still fine. The date is also fine. The only reason the Date needs to be mentioned is to check if the photo is a recent one. But as long as you do not receive any notification from NTA, you are good.
