So did I!!! And what's more I thought it had been withdrawn except for that testing on the IOW as it doesn't work properly. I doubt it will make it onto my Samsung as that is just over three years old and it won't work on phones older than that.
On another note entirely, I have just used the hair dye I got from Ideal World when we had the shortage. It looks fine, slightly darker than my usual colour. I did think it had a pretty awful smell but no biggy. My usual colour came back onto the Superdrug website so I got a couple of those just to be safe.
