I have tried to get importing attendances to work with no success however during that process I noticed that even if importing new attendances for new dates fails (without any error) it is possible to import new attendances for the days that already have attendance data if the sign in and sign out times are same as for previous data (see screenshot).

So it seems that something in validity checks of importing attendances fails because it is possible to import invalid data but not valid data.
