If you read my posts you would realize that I have said from the start that it was like it had a time bomb. There is supposedly a fixed version on the EU Apple App Stores with a date of 19 Apr 2021. It has not appeared on other app stores as of yet.It has nothing to do with the iso version. I have run the app on my iPad 2, my iPod 5, and my iPad Pro. I have never updated anything on the iPad 2 or the iPod. The environment was never changed for those devices since it last ran. Therefore, it must be in the app itself. It crashed on every thing; even my android phone. It‘s like it has an expiration date. The only way I could make it work was with a hacked android breeze app. But I want it to work on my iPad. Yuneec doesn’t appear to be worried about their customers as the problem has existed for some time. I hope the pros are taking notice and their business elseware. I don’t like law suits but it seems class action suits are the only way companies will stop this bs. Fix the #@$#*# app, Yuneec!!!
