You see I’ve done this before and done the same thing again but this time it does no difference. Every time I change it it would not actually save. The servers are all correct. It’s just that it feels like apple isn’t allowing it.. like last year I’ve done this on iOS 11 on iPhone X but for the past month I’ve tried and it doesn’t seem to work on the my current XS. The manual settings I put in the i settings don’t actually save. I would select the manual, delete my old, put the current one I need and it would go back to automatic.
