To clarify what that means, we’re seeing a small display issue if you have, for instance, a checkbox question at the start of page 2. When interacting with it in iOS the options will appear all white (with the default survey theme at least). The option is checked, however, so it appears to be possibly an issue with iOS’s handling of the checked attribute.
If you advance past the question and come back the checked options will appear like they should.
We’ll see what can be done with this one. Stay tuned for updates!
Should be fixed now!
