So, props to the developer for updating their app and keeping it fresh; HOWEVER, in the latest automatic update (99.9% of iPhone users have their apps update automatically), my four years of lease mileage data are gone. Checking Leastimator Store reveals that the developer stated to export the data prior to upgrading. Unfortunately, this was never an option. Users just don’t check Leastimator Store anymore prior to upgrading their apps.
I would completely understand that perhaps the developer didn’t realize this, except that ethical app management dictates that you warn your users that a major upgrade is coming and data may be lost. Lease mileage isn’t a big deal - I’ll get over it. But to Leastimator developer: unfortunately, you messed up. Your long-time users would appreciate a “mea culpa” here.
