YLXD16YL - not pairing with remote control (YLYK01YL)

I purchased on Amazon Italia n ° 2 LED Ceiling Light 450 (YLXD16YL) visible at this link: https://www.amazon.it/gp/product/B083ZFYG47/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1.
Problem: I cannot connect the supplied remote control (YLYK01YL) to either of the two lights.
I then tried to connect the remotes in question with other Yeelight lights and I was able to pair correctly, so the remotes are OK; unlike other remotes that I already had these also do not connect to the new lights.
I hypothesize therefore that the probkema is linked to the firmware present on the new lights, which is the version: 2.0.2_0048.
Can someone help me ?
Downgrade, but how?
