This is one area where I’d imagine there’s a high chance of rejection, because it happened to me.
When it asks for a photo taken within the last six months, make sure you actually take a new photo. Don’t think, “I’ll just use the one from January — I still look the same.”
What I discovered is that when you upload a photo, the file can contain metadata showing when it was taken, and the system may be able to reject it based on that.
Just some helpful advice: take a new photo and upload that. If you can avoid it, don’t use an older photo because of the metadata.
