Well written and I don't blame you for leaving this forum. You certainly have not received any help from this forum, as there appears to be no solution to the problem. We have not heard one peep out of Apple on this matter, one voice of reason to give us hope that this will ever be resolved. They have put so many of us through pain with our photo libraries without resolution.
I think of all the video and photo software companies I'm involved in and how those companies join in on discussions and help to resolve user issues, but not Apple. They are in their little glass house and nobody can actually talk to them. If you book an appointment with a so called expert, it's like this is the first time they are hearing about this issue. Obviously they don't use Apple products or they would know first hand. How very frustrating this is, having been an Apple user since 1989, a holder of their stock, but no more. Thanks a lot for your lack of support on this, Apple. I know this message will be sanitized, deleted immediately. Maybe a few will read it.
