Well said.
Lots of people are reporting here that the Recents (aka Camera Roll) functionality has disappeared from the Photos app with iOS 18. Others are stating that it has not. Assuming that we are all rational beings, there must be an explanation for these different perceptions. I think that the most likely explanation lies in the different ways people use the Photos app. For example, some people sync their photos to iCloud, while others (including me) do not. This would result in differing user experiences. Similarly, some people sync some of their photos from their Macs (or other devices) to their phones and others do not. That too would result in differing user experiences. There may be yet other differences in the use of the Photos app which would affect this issue.
The bottom line, however, is that for a sizeable number of users iOS 18 (including me) has introduced a catastrophic change. Some people on this forum report that they have found a workaround, using the Camera app. Unfortunately, this does not work on my phone (as I have mentioned earlier). I have no idea why.
