Crucial RAM 4GB DDR4 2666 MHz CL19 Laptop Memory CT4G4SFS8266 — https://www.amazon.com/gp/product/B07HP78DZ5 worked with my DS220+. What was strange about it though is that it took multiple resets for the NAS to pick it up.
Yes, sometimes you need to leave it overnight. It does some background checks before it accepts it.
By overnight does that mean about 12 hours?
Yes

I’m trying this in my DS220+ : Kingston KVR26S19S8/16 DDR4 16GB 2666MHz CL19 SODIMM 1Rx8
Blue led is blinking for over 20 minutes now. I think it won’t work. It matches the specs (2666 MHz, CL19), what should I do?
Did it work at the end?
