Hello James Davis,
We will be launching our Beta 2 shortly. We will announce it on all community sections on our site. Unfortunately, there won't be a lot of bugfixes in the TileView with this Beta 2. We will continue the bugfixing of the control starting now, for the official release. We can probably prepare an internal build for you and send it to you as soon as we have managed to address most of the known issues.
