I actually didn't have problem uploading the IDs. My problem was I didn't know why it did not verify. So I emailed CS instead and they responded within 24 hrs.
For me there was an actual mismatch from my ID with the info they have on file, (DOB for me), therefore it kept saying Photo ID not valid.
I would suggest to email them directly as well and ask them why. It worked for me so.
Thanks and good luck.
