I got the patch directly from Netgear to fix the issue with V4.6.8.2_2.1.9 not being able to access the router admin via web or mobile app. The patch fixed the issue but now I'm having connection issues. It really rears it's head when I connect to my work's VPN and remote desktop via Cisco Connect Anywhere. It constantly kicks me off the remote desktop now. I have informed Netgear through reddit DM, in fact the same thread where I received the patch. Now I am being ignored.
I'm so disappointed that I bought such an expensive router (RBR852) and I'm having these issues. It's beyond frustrating. I found this thread because I was considering trying to manually go back to the last stable firmware that they have on the website, but I don't want to mess it up even more.
