Did you read the features list? Did is say time stretch anywhere? You paid for what you got and that’s a silly complaint.
If you bought Auria you’d probably be complaining at their forum right now saying “What, no MIDI??? I should have gotten Cubasis instead” (which would also be silly).
Just man up and take responsibility for your actions, you bought something without making your research, now deal with it, it’s your own fault.
