Does not work since 2021 arrived – FlagFit 2.0 Review

Since January 1, 2021, this app has not worked. Whenever I try to pen the app on my iPhone the page flashes and returns to the first app page. It no longer syncs and is losing time. I had been very pleased with it up to this point. Hope you can fix it!
