I joined Pottermore and have been locked out at the beginning of chapter five with the picture of Diagonal Alley with no idea how to get to the next picture. I have collected objects (not sure if I found everything though), and read everything available, so am not sure what I am doing wrong. Anyhow, please add me as a friend. I am SeerRose29498 ~ there was a choice for a cauldron name, too, that wasn't so bad, but thought SeerRose would be easier to remember.
For each page make sure you zoom in twice and look around each zoom for things to collect. I would try to move my mouse around everywhere and still missed things! Potions are really frickin' hard. I've already managed to blow up one of my cauldrons. Any potion ingredients you find are renewable after you use them. You just have to go back to the page you found them and get them again. Ones you don't find can be bought in diagon alley.
I haven't used the desktop yet to try the site. I see now the iPad is limited with the stylus and lack of arrow keys. How many items can be on a page? I have 8 things in my chest so far.
Will see the eye surgeon in the morning. Still have issues with flashes, black and white dots that look like patterns. Wednesday is the new doctor then will get his referral for the specialist. The insurance is certainly convoluted for being so stingy about payouts.
If you're at Diagon Alley, zoom in once (not all the way to Gringotts), there should be a person standing in the middle of the road with a cloak on. On the ground is a piece of paper (your shopping list) that you need in order to proceed to Gringotts. I got hung up at the same spot!
