@errol-1 Now solved - you need to use the '+' option to choose Windy in the apps list and then hold the Windy icon to choose between premium and non-premium options.

Doesn’t work for me after installing iOS 16 on my iPhone 11. I can add the app to my home screen but it just keeps telling me that it is not supported and that I should install the app for iOS 14.
That’s a pity as I like Windy and was a Premium member but from now on my go to will be the Met Office app as at least it works on my Lock Screen.

EDIT. After a false start installing the ‘other’ Windy app I finally managed to get the app on my Lock Screen by adding a widget, not through the customisation option - which still gives the message above btw.
However, all that gets displayed is a message that I should upgrade to Premium!

Back to the Met Office app for my daily weather updates …
