I made the mistake since I am in the States last month to do a withdrawal on Sept 30th which I didn’t account for the time change which put the request a day ahead on the 1st! So I had to wait until Nov 15th!
Now that we have automatic withdrawal, hopefully this will help with time travellers

As far as what camera you need, there is no set rule for what you can use as long as it’s at least 2MP in size and the quality is high enough to offer for sale. Unfortunately, even if you can capture 2MP pictures with your phone, the quality is rarely good enough to sell.
