Same here. As far as I can tell both the Insider Hub and Microsoft store use my microsoft windows log-in. I have not been able to see anywhere else to change logins outside of Windows itself.

On a NVIDIA GeForce RTX 2060 on build RTX 1.16.30.57, did not see light emitted from lava trying two different RTX cores.

I've just attempted again to join the RTX Beta and it only enrolls me in the regular Beta. I have a GeForce RTX 2060 and meet all minimum requirements. I've uninstalled, reinstalled, opted out, opted in, even uninstalled the insider hub and reinstalled it. My husband with an identical system is enrolled in the RTX Beta. I'm not sure what files or pics you need from me. Just let me know and I will be happy to comply. 

I need to check on the insomnia but mob spawning is on. It is a variation of indoor and outdoor. Difficulty is set to hard.

Experiencing this same issue after the most recent update. Newly created books do not stack in inventory or chests. Stacked books, from prior to the update, cannot be removed from chests or separated by using the "pick up half" option. 

I have experienced this issue on Minecraft for Windows 10. The dragon was there when we entered the end but after dying a couple of times when we entered back into the end the dragon was gone. The return portal is there and working but no egg, experience, ..nada.
