Update to my previous review: After quite a while, iBird sent a response attempting to justify their taking my 2021 purchase away and forcing a subscription (or a repurchase) on us and offering a free year of their new service. Basically, the response they sent is untruth after untruth. There is no functional way to activate a "Previous Owner" option for a year, so they are not even offering this. As I've been requesting this restoration for months now, their team is clearly not "committed to assisting" me as they said. Nor are they actually "providing continuous service" to users, but exactly the opposite with this new policy.
Fine if you decide to move to a subscription service for new users, but to not allow purchased access for those of us who "bought" the service less that three years before is basically a scam. Why should any buyer even trust that you won't do the same thing for an 'improved subscription' or something like that in three years and make everyone repurchase their lifetime subscription? So you not, you don't have my "understanding and continued support." I purchased this app in 2021 and it was sold as lifetime access. This year they abruptly rescinded that and refused to restore the download. They now are asking for $59.99 for the same thing I purchased three years ago, why should anyone believe that they won’t do the same thing in three years, effectively charging $20 (or more) per year for use?
