I recall that those also depend on language/region settings as well, in case that might be in play in some way.Received my XS max yesterday. With IOS12 did they remove the AM/PM indicator next to the time in the upper left corner? My iPad Pro 10.5 with IOS 12 has the am/pm notation.
Or devolved... lol (became less useful to accommodate a hardware design change)Apple.com/feedback ? About the only option I can suggest. There is not enough room for everything with the notch. I could also complain that I do not know if I have an alarm alarm or not since that icon is hidden. As is the battery percentage. But the software evolved to support the display.
