For warranty, you can try to check the info here:-

My showing info as screenshot until Oct 2021. I believe it means warranty covered 2 yrs until 2021.

I got my devices and turned on 22nd. Next day 23rd, it showed warranty until 2020, today I opened the link, it showed 2021. Maybe just need to wait for 1 or 2 days to let them process.

I will check later and hopefully will not go back to 2020.

Your screen got SP. right? Scratch on SP? I dont think so to claim for SP.
