Just downloaded the new IOS18 update. immediately ran into problems. in particular the new Photo app is dreadful. It is cumbersome to navigate, quite unintuitive to use and, frankly, a mess. I cannot imagine why Apple thought this an improvement compared to the simpler and much more usable previous version. other problems include difficulties with location and home screens on the weather app, and others. i was about to upgrade my iPhone (XR) to the iPhone 16. I am now seriously questioning the sense of that given how cumbersome many of the apps have become.
