Fitbit Premium sleep stats diagrams are buggy (sleeping HR, and Est Oxy Var)

[ekivisik]

Sleep HR graph shows only a small part of sleep time - ends at 23:59. Estimated Oxy Var graph shows full time on the horizontal axis, but the graph is drawn only partly - the line ends few hours before the sleep time ends. I suspect this is related to the fact that I have intentionally manually set different timezones in my phone and Fitbit app. I always keep Fitbit timezone at UTC, but I change my phone timezone as I travel. There are some more bugs which have appeared due to that (mainly sleep logs related), but I have found workarounds for those. These incomplete graphs, however, should be fixed by you, thank you. After all, this is a premium feature.

I have screenshots of the buggy graphs, but I don't see a way to post them here. Will send by e-mail, referring to this post.

Did you ever find a solution to this problem. My Versa 2 sleep restoration many nights only shows data up until 23:59

I suspect that it happens because the software is confused by the different
timezone settings. Because I travel a lot between timezones, I have set up
a constant timezone for my Fitbit app, so that it records any activity only
in one timezone, not changing frequently. I would be happy if the
developers checked this hypothesis by testing, and if this is true, then
modify the software code to be able to represent the stats as desired, not
messed up by the mismatch between "Fitbit constant timezone" and "Phone
timezone".
