So I read down some more threads and found that others were having this same issue, which was resolved by deleting their data on their body stats.
So I tried that, and sure enough, the sync worked. How can we contact someone in support/tech to resolve this issue?
I don't know if I'm never going to be able to enter body info without running into this issue, or if I have to enter it only into the online version, which it seems some have done to resolve it, or what the solution will be.
Anyone know how to contact someone at FitDay to help with resolving this?
