Photoroom no longer works due to too many changes

photoroom changes, I have subscribed to photoroom for 4 years and this year I hadn't been using it because I was busy taking care of my parents. My subscription renewed in September and I started trying to use it again. They have made so many changes that I no longer understand how to use it. If I ask for help they may get back to me a day later sometimes a week later. I asked apple for a refund but I was passed the amount of days they allow for refunds. I've been struggling to learn how to use it with the changes but I've wasted so much time. I have figured out how to get my photos in and remove the background but sometimes it takes too much of the background and sometimes it doesn't take enough. I used to know how to fix it but I don't anymore. When I ask for help they send me a video with no sound and I can't understand what they are doing. I have wasted so much time with this. Does anyone know how to restore items that photoroom shouldn't have removed? I used to be able to edit and bring back what was deleted that shouldn't have been deleted or delete items that photoroom left in that I didn't want in the photo. I shouldn't have to learn again an app that I was using without problems, it seems Apple doesn't understand anything, and the employees don't want to help walk me through.
