We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
I think your browser just has a low local storage limit set. We now will suppress this error, meaning auto-save won't work if basically beyond the configured local storage limit.
