Unable to update to 12.1

So today I saw that the 12.1 update is downloaded and asking me to install it. But, when I do try installing it the screen is stuck at the Cyanogen Recovery.

The usual options in recovery screen are displayed, why isn't the OS updating?

FYI - My OPO is rooted and also has TWRP recovery installed. I also tried disabling the Update Cyanogen Recovery option but the same option.

Any assistance would be great :)
