but...
In Future dot releases we are going to address this issue by adjusting the dates to only return Buttons between certain dates.
When I spoke with PayPal, they did confirm that they only return 100 buttons *at a time*, but we could get another 100 buttons, then another, if we adjusted the time frame by increments. I guess my question is will you be doing what Dani said above and give us a way to adjust the time frame?
