Thanks for the report, and sorry this has been an issue! Amazon keeps tweaking their page layouts, which causes these blank-page issues to crop up. I just pushed version 1.1.4 which should fix.

Once you update, do a hard refresh (Ctrl+Shift+R / Cmd+Shift+R), and if that doesn't work, clear your browser cache. Give it a shot and let me know how it goes! If it's working well, an updated rating would be much appreciated ⭐⭐⭐⭐⭐
