Worked, flow was a bit odd. First tap of redeem button didn't show anything. Second tap gave an error (didn't record it). Third tap gave an already spent error. This was on amethyst client. Went to ln address set for zaps. Thought I thought I had to claim at cashu.me

So overall seemed fine. Not sure why I didn't see confirmation message that it was redeemed in amethyst. But I believe that's the NOSTR client.
