The first thing to try when this happens is to restart your phone and then restart your fitbit using this procedure:

Give this a few tries as it doesn't always work.

Oh, by the way, most fitbits can only hold a week's worth of data between syncs (the Alta is just 5) so you be losing some data. If this has happened to you then you should still get summary data for those days on your dashboard.
