Oh weird. Thank you for this! I can't figure out why the backspace code isn't working, but I'll have a look. You can press 'escape' to cancel a code half-typed and it *should* be deleted next time you click on 'redeem', I think.
Great, thanks! Can confirm that hitting ESC works to cancel and clear a partially typed code and try clicking redeem again! Tested today on my last redeem and it worked just fine to do that.
