Yes, I have the “cloud”-y thingie close to the WhatsApp icon, meaning is offloaded. When clicking on the item to “load” it again it tries to do just that, only to give me a “Unable to download” message (or something similar) a few seconds later. I’ve tried searching for the app directly in the AppStore, I cannot find it anymore, presumably because of that older iOS I have running. Forgot to mention, the same happened to me with the Google Maps (?!) app also last year or so.
