In V5, an inquiry shows "Our turn to reply" and the buyer has changed something. How do I see what they changed?

1. Open the inquiry detail page (for example SIM-INQ-S0010-01) and check the status tag at the top to confirm it shows "Our turn to reply". 2. Click the orange button at the top right, next to "Discuss": "Buyer made changes, click to compare". 3. The screen shows the differences between the buyer's changes and our version. Go through them item by item before deciding how to respond.
