Zoe don't use self reported symptoms for their prevalance estimates afaik. I think they send out a few thousand random PCR tests and use that instead.

AIUI they look at how many people who have symptom X also test positive and then make a guess about prevalence based on how many other people reported symptom X.

The whole thing smells distinctly unsciencey to me. But great for generating press releases.
