I have had messages asking me to upload photo ID to be able to carry on receiving Shopify payments to our online store but when I upload both a drivers license or passport picture, it repeatedly comes back with a 'The photo ID you uploaded was not valid' message. I am uploading it in the requested JPeg file type and I've tried sending different sizes but nothing works. I am now worried that the payments function will stop working on the site. There is no information anywhere that tells me why it has not accepted the uploads. Can someone help?
