I did not know that, thanks. But still - if I have to research now how to do that it‘s still going in the wrong direction, no? Besides, it‘s rare that Apple gives a choice, usually you have to adapt at whatever they decide.

So Apple shouldn’t make things more customizable?

There is no way to get the old Photos interface back.

I see mail now has mandatory images next to each mail item, how can that be turned off?

Settings -> Apps -> Mail -> Show Contact Photos

Wow as simple as that, thank you.
