Ever since the app update in mid-March my Blaze stopped tracking sleep. I've done everything to troubleshoot the problem.... uninstall/reinstall app, reset the Blaze literally 60+ times, played with all the settings...it will only give me basic sleep after I manually enter which defeats the purpose of a sleep tracking function. I have issues sleeping, so I use the Blaze to journal my sleep hours. Manually entering is not accurate and doesn't provide me data analysis. Didn't experience these issues before all the recent updates. Could this possibly be a firmware issue?
