Update to say I have found the settings button! For anyone else like me who was searching for it, it's in the same place as before, just hidden at the bottom. When opening the meatball menu (three dots) in the toolbar, scroll down to open the full list of options, then scroll down a second time to show the settings button, which is now below the 'Print' option (please see attached screenshot). Personally I don't like the new placement of the settings button, as it is not very intuitive to find and is now slightly harder/takes more steps to access. This is somewhat annoying as it is often the main thing I am looking for in the menu, certainly much more commonly than I am looking for the print button. If possible I would appreciate it if it was either moved further up the list or if we were allowed to individually customise the order of the items in the menu, though I'm sure neither can/will be done any time soon. Anyway, hope this helps someone else in the future! :)
