I'm having problems getting a conditionally required setting to work with a select_one question. It's set up as below - when I 'validate' this in the desktop app it works as it should, but when I test on an iPhone the 'required' condition is ignored, and it allows me to save the survey with 'test1' = 'yes' but 'test2' is left blank. If I change 'test2' to a text question it works as it should on the phone - i.e. I'm not allowed to save the survey when 'test1' = 'yes' and 'test2' is blank. Is this a limitation with conditional requirements and select_one questions?
