I am also Pro user and also think it is breaking of promises to not provide some features to "All access lifetime" plan . But I will not do hasty decisions right now. I even tried "Premium" subscription, it is much cheaper in Google Play, but possibly it depends on country of residence. In general I think the best option for company to find compromise and provide upgrade from "Pro" to "Premium" for price satisfactory for people you promised lifetime updates for free. It is definitely not $80 and not $50 with promocode available for all.
