Glad to see I'm not the only one who uses this feature for business tracking purposes, although not so glad to see that there's no easy workaround.
Has anyone tried this suggestion of turning off location tracking, rebooting, the turning it back on? That certainly sounds like it will delete all existing records, which would rather defeat the point if there were records I wanted to be able to look at, so I'm reluctant to even try it.
For what it's worth, this data not being accessible goes beyond just being loss of a very useful feature for those of us who are bad at time tracking for work; the fact that there is fairly sensitive data being stored that is completely inaccessible to the user is fundamentally problematic.
