Hey, welcome to the fun!
Your camera image doesn’t look excessively blurry to me out at the edges…because of the fisheye effect of the lid camera lens the outer reaches are always a little blurred looking.
This is mine:
And your drawing looks very clear.
Sometimes the QR code sticker gets stuck slightly out of range (they do that to keep people from having to remove the sticker if they do a large engrave, but it does make them hard to read sometimes).
If you click on the name of the material, or the words Unknown Material, over the top of the left thumbnail column you can enter the correct material just by clicking on it. If you need to search for one, just type Medium Draftboard or Thick Walnut in the little magnifying glass search area.
And it sometimes helps to rotate the sticker around into the upper left corner to let it read better.
