I did not experience any blinking lights or stalling in the engine. No rotten egg smell, no smoke, no sluggishness. Just the light that was tormenting me.
I took it to the dealership and they replaced the cats. I asked if they were poisoned because I was worried about a larger problem. They told me it was not poisoned and they had just failed.
Replaced under warranty at no cost to me. Very satisfied with my experience.

O2 Sensor on a 2011 Jeep Wrangler Unli-Rubicon
I'm having the same DTC P0420 on my 2011 JK Wrangler UR. Do you know where to purchase the MOPAR O2 sensor? Thanks!
