This is a very good update, and I was able to Activate after the update installed. The Mark as Read, Shortcut Keys, Bedside Mode Filter are all great additions to the app (in that order).
I had an issue with this release and 4.6.0.168 on my Bold. Hats off to the guys for being all over me to get details to try and resolve the issue. I know they are still working on it. But I was very pleased with the level of support for this product.
