Sky replacement is greyed out, HDR does'nt transfer with export

Hi,

I've encountered a couple of issues with photoshop.

I downloaded photoshop beta a while ago and everything worked fine, apart from the annoying popup boxes in the app telling me I have to update to the latest version to use some of the tools, which I couldn't close for some reason.

All of a sudden I couldn't use the sky replacement tool anymore, the option was greyed out. I updated to the latest version with no results. I could still use the sky replacement tool in the regular version of photoshop althoug you couldn't find the the regular version in the launch pad of my mac nor could you choose the option 'edit in photoshop' through lightroom, only 'edit in photoshop beta' was an option. So I have to export my files from lightroom and open them again in photoshop, a bit of a hassle but not a huge problem.

Then I noticed if I use the HDR function in lightroom, for which I'm really happy this got introduced because it makes your images so much better, and I want to edit them in photoshop afterwards the HDR settings don't get transfered to photoshop for some reason and this also seemed the cause for the greyed out sky replacement tool. If I export my files from lightroom the HDR settings also don't get transfered, even if I tick the HDR box in the export settings, but I can open my files again in photoshop and use skyreplacement.

Does anyone have a solution for these annoying problems?

Cheers
