$99/US for Ultra Lifetime, $20 for "just" Ad Free Lifetime.

I'm actually used to the opposite. Subscriptions I would kind of expect to carry over, because they were intended to cover a very specific length of time, independent of any versioning. Any lifetime or one time purchases are exactly the ones that I would expect to not carry over. ( Even though I would love for them to. ) Because in modern day, lifetime mostly gets interpreted as the lifetime of the major version or product. It's not really even meant as a defense, just an acknowledgment that that is the norm, for better or worse.
