Extras! Where the heck are they? I like to share to 'Rowi' and 'Photobucket' within the photo app.
You can find the "beta xbox live extras" in the market still, but its only for avatar editing now. Easiest way is to just go into games hub, click on "avatar" and it will take you to the app. All the rest is built into the hub now.
There are some glitches in the system, but we do have to keep in mind this is a preview build which is not only not finished, but certain things are not implemented which will be part of the final release.
That being said, here are a couple glitches I've come across quite frequently. Both seem related to the same issue:
1 Tile edges will render incorrectly while scrolling/flipping sometimes.
2. in pictures folder when scrolling down quickly you will see many duplicates of the same photo being rendered. Once you slow down or stop scrolling, they will load the correct thumbnails. In the NoDo build they just wouldn't render till you slowed down, and I almost prefer this.
Seems like a general rendering issue that most likely wont be in the final build though so I'm not worried about it.
