Brit here. I refused to install the NHS Covid app until they revamped it to improve privacy. I once received a notice that my device recorded a beacon which was later submitted as from a infected person, but it didn't require me to take action as it was otherwise outside of criteria (either distance or duration). They eventually removed these warnings as they are not helpful. If it informed me that I had to quarantine and/or get tested I would definitely do so.
