Dude. Your author is dead wrong as many western analysts usually are. No. 1, the first J20 sporting WS10 was first spotted in 2017, not "initial production" versions as your author says.That article is from 2020 and it clearly states that the J-20 is still using AL-31 engines. This means that you were wrong when you stated that the 2019 J-20 used the WS-10.
Anyone can post an article. Show me pictures of new build J20s flying with AL31 turbo fans.
We first saw prototype 2021 testing WS10Cs in 2017 then production airframe started rolling out by 2019. There is plenty pictorial evidence to support this. Show me your evidence.
This article is also from 2020:
Imagery of a J-20A carrying the serial ‘2021’ that surfaced in September 2017 also revealed new serrated engine nozzles for the first time. This confirmed that J-20 production had shifted to include indigenous WS-10C engines built by Shenyang Liming. These featured sawtooth exhaust feathers to help reduce the aircraft’s rear hemisphere radar cross-section (RCS). These new engines delivered a much-needed increase in thrust to around 147 kN (33,070 lbs). Reports at that time suggested that these engines featured thrust vectoring, but this was never confirmed.

Images that were released in November 2019 showed J-20s in yellow primer, with the same sawtooth nozzles. These were claimed to be evidence of the J-20B by Chinese media. However, these aircraft were actually additional J-20As with standard WS-10C engines. These engines were also incorrectly identified as WS-10Bs, as that engine is mainly intended for the latest production batch J-10Cs and J-16s and lacks the sawtooth nozzles.
