I am crazy, or did the ‘select all’ button disappear with latest update? Why would this be a choice??

my email app seems to have lost ‘select all’ functionality…the only fast way of marking multiple emails as read or whatnot I can use is swiping down the list on the left. I cannot figure out how to select all as button no longer appears on top right and I haven’t been able to find it. Googled the problem and it took me to a apple forum page clearly showing where the button should be. What am I missing?? They cannot have actually gotten rid of that function?
