Paid for the app several years ago. Nothing but good things to say about it. Until September 9, 2023. My app suddenly disappeared. Removed from my Apple account. No longer appeared on my phone. Purchased the app again. And all of my calendar events suddenly reappeared. But everything I saved for repeated use was gone. Information I saved for several years. Now had to be re-entered. And at the cost of re-purchasing the app. I am out raged. But who cares right?

I never responded to the last Birdsoft developer response (thank you for that!), so I thought that I should finish off before any next steps. 😌 I took your points and appreciated almost all of them, although I do not know that it is fair to speak of my expectations for ā€œallā€ apps. I just know that when I buy one I want it to continue to work. That is just the nature of being a client or consumer, and understandably so. However, I did understand what you were trying to convey. • I expect that you did send out the app update that you mentioned, but the version of Extreme Agenda I was using was the add-on that I purchased through Extreme Week (purple icon). So I did not receive an update there. • Anyway, since I really like that product I am happy to try out the Ultiplanner (sp?) and possibly purchase it. I just hope that this new app will allow me the same ability to display my engagements as icons (instead of words), and that the ā€œCategoriesā€ will also sync across all my iOS devices along with the other data (which Extreme Planner just never did somehow). Looking forward to the experience! •••••••••••• 3/1/23 There is an ongoing glitch with this calendar that occurs while you have a window open and are configuring an event for the first time (so it is not saved yet). Although the original version of this app did not have this issue, the window that opens when you are creating a new event is quite ā€œbouncy.ā€ By this I mean that the entire date configuration window display can be pulled downwards just by touching the screen and dragging your finger downwards a bit. Then when you let go, the window pops back up to the top of the screen like a rubber band. In the process, anything you entered into that window almost invariably gets erased and you are left with an empty default window. It is as if you had just opened a new event window and had not worked on it yet. So you have to create your event again from scratch. This is a problem not because you are going to intentionally pull downwards on the window while you work, but because it is so easy to do so accidentally. So you have to be so careful about how you touch the screen now and this is like tiptoeing with your fingers. As a user, this is uncomfortable and unnatural. • It occurs to me that perhaps this is what some users were referring to when they mentioned ā€œdisappearing eventsā€ in their reviews of this product. • I should note that this issue did appear to be fixed at some point two years ago but the problem returned again after a week or two. I just never said anything about it until now.
