To me, the differences between iOS 10 and 11 isn’t huge. One would think that it would get more stable. iOS 11, to me, is the most buggy update in years. I cannot recall how many times iOS 11 has froze, how many times the notifications are misaligned, or when I’m listening to the SiriusXM app, the wake screen sometimes shows the audio controls of the XM app, but many times it shows Apple Music and a song from my playlist even though I’m listening to XM. It is sad that I had to delete the stock calculator app because it is barely usable to me without making many mistakes. Really, a calculator? I haven’t downloaded the calculator again to see if it was fixed in iOS 11.1, but still I guess one would think refinements and stability would be happening versus instability. I guess I’m just ranting. I can call Apple but reporting dumb stuff like a calculator is irritating. Does Apple really not know of these things? As a big Apple fan, it’s frustrating. I just bought my second Apple Watch. The SS Series 3 with watchOS 4.1 is fantastic. Very refined from earlier versions.
