This should be fixed now.  Please confirm that you can see that drop down for price increase and price decrease.

You can sort by price change in your collection but it is based on the recent price change in the value, not in the value since you added it to your collection.  There should be a "price change" option in the sort drop down on the page.

It is on our roadmap to add in January.  Hopefully it will be live on the site soon.

The grades are a number grade that a 3rd party company has given the card based on it's condition.  Companies like CGC, PSA, and Beckett are the main grading companies.

Unfortunately that is something that Android and the browser changed. After you click “upload” photo button on our site, Android and the browser decide how to give the user those options. It looks like they recently changed in some versions of Android (maybe just specific phone brands). I’ve heard a couple people mention this in the last two weeks, but unfortunately there is no change I can make on our site to bring that back.

It is very annoying for sure. It only makes sense to allow users in a mobile device to take a picture right then instead of using their existing photos.
