How to switch languages in Catalina
On my previous iMac with Mohave I had an icon (British flag + the word British) on the right of the upper menu bar which I used to switch to French or Welsh and to launch the keyboard where I selected the accented letters required. This is missing on my new iMac with Catalina. I've added these two languages in the Preferences/keyboard/input sources and ticked the "Show input menu in menu bar", but I see nothing in the menu bar. Can anyone help please?
