******* EDIT - I'VE JUST DISCOVERED THAT THE DISCOUNT FOR LIFETIME IS NO LONGER OFFERED, WHICH IS A PITY ********
I've been an Infuse user for years and purchased Infuse Pro 5 a while back (and I think 4 before that). I'm now running Infuse 6, on a 1-year sub (can't remember if I paid for that or if it was the free 1-year upgrade offer from 5). I noticed that it's nearly time to renew that 1-year sub, so I thought I'd have a look at upgrading to lifetime. From what I'd read, I thought there was a discounted version of the lifetime sub available to previous pro 5 subscribers, but I can't seem to trigger that to work. Even if I have 5 Pro and Infuse 6 installed at the same time, the only lifetime in-app purchase I'm offered in 6 is the normal price of £54.99.
Am I doing something wrong, or does the discount no longer exist as a thing?
