For those who face uploading errors on KYC despite being at JPG, GIF, PNG, TIFF or PDF formats. It could be due to the system being unable to recognize the file properly as it was taken by phone camera.
Please attempt to use a different browser (Firefox or Google Chrome recommended).
If switching to a different browser does not fix the issue, do try to take a photo using a different device. Devices such as webcam, scanners or laptop camera would do the trick.
