When learners are entering their address info in the e-commerce area as part of the purchase process, they receive no feedback as to what is missing or incorrect when it won’t move forward. It just shows a circle/slash and does not allow them to proceed but gives no feedback about what is missing. Often, it’s an extra space after an entry – something many e-commerce platforms seem to be able to handle. (We have added” Please make sure you have completed all Required fields to Proceed to Checkout, and that there are no extra spaces after any of your entries.” to the text at the top of the Shopping Cart view, but helping the user understand what they are missing or doing wrong would be better.)
