Good - But what happened? – FlagFit 2.0 Review

I’m an iPhone user, that recently found out about some health issues. I came across this watch and wanted to try it to get me & help track steps, health info. I just did an update to my phone but now the app won’t even stay open??!! What happened?? I used it daily for my sleep patterns, Ck health and steps..... But now I can’t! The app won’t stay open at all, it immediately shuts down each time I try to open it to use. So disappointing. Was overall pleased with this product but now - not at all. Also wish the app would track historical personal health info. PLEASE DO AN UPDATE AND FIX THIS!! Would’ve rated higher but can’t. Watch decent, app not at all.
