When putting multiline label (with linebreak set to Word Wrap) into a stack view, the label immediately loses the linebreak and displays the label text in one line instead.<
In my case, I followed the previous suggestions, but my text was still getting truncated to a single line though only in landscape. Turns out, I found an invisible \0
null character in the label's text which was the culprit. It must have been introduced alongside the em dash symbol I had inserted. To see if this is also happening in your case, use the View Debugger to select your label and inspect its text.
