O2 Sensors - Anyone having trouble with them?

Hi All
So I have got the CEL light on again this time with fault P0036 - Heater Control Circuit Bank 1 Sensor 2.
I had this sensor replaced in December 2019, that was throwing the P0041 fault. My mechanic is following up with supplier.
I've heard that there are a lot of dodgy parts around these days. Is anyone else having issues with O2 sensors?

Like some of the lads here in the US I went with the OE Bosch ones that I bought on Rockauto.com, I changed all 4 at ~72k miles during the CC (2 years / 6k miles ago ) and so far no issues.
I did get the P0036 code about 3-4 months ago on my Golf R with 18k miles and the mechanic and I think it probably went early as I’m tuned for and used E85 on that car, other than that they should probably last longer

.
Having to change the same sensor after 2 years doesn’t seem normal at all, did you go with OEM/Bosch back then? Are you by chance catless?

My mechanic said that it came in a Bosch box and seemed legit. Nah not catless, only thing done is I had the center resonator removed last december.
