I’ve also received the email, have the original, and don’t see a discount. (I assume that Daz still isn’t recognising previous purchases: has that been fixed. I’ve given up using the store except for new stuff.)
Well with the Baroque Grandeur reissue, we did the same thing - and after a bumpy start I think that was all working fine on both the original BG product and the bundle purchases. So it’s certainly doable, it just needs a little coaxing still.
I assume the same thing is happening here. Rest assured it will be working ASAP, I’m on the case and can only ask you all to bear with me on this
