I'll explain here since I don't have Discord :
Basically, on Steam, once you've played a game you freshly bought for a bit (I think it's 2 or 3 hours; I currently have 3.5h on the Steam version of SNS), the platform will propose you to leave an evaluation (you know those messages with the blue thumb up or red thumb down you can see on a game's store page) to know what you think of the game and if you'd recommend it.
Right now, you can complete the message (and choose thumb up or down) but when trying to submit it, there's an error indicating "the product isn't available in your region", which is probably due to the store page of SNS not existing anymore, despite the game still being in the library of those who bought it before the false claims.
As for the "Sonar-Saiko", the best way I can explain this is that she always spots you even when she shouldn't or didn't before :
those are mainly when you're behind her, far away from her and/or crouching. In the previous build, you seemed to be able to evade her with those (principaly with the "being behind her" part), it's no longer possible in 2.1.2 where no matter where your position to her is, she will always spot you as if she had a spidey sense telling her you can see her. She still can't see you in lockers and the rooms under the stairs, tho, those still work.
The problem seems to be more prevalent in Normal, Hard and Yandere mode. I can't really tell if there's much change in Yangire mode, tho...
As for being seen through things and wall, that also wasn't in the previous build. I used to be able to use the bookcases of the library as cover, now she'll always stop me if I'm not in a locker in the library.
And for the "through-wall" problem it seem to mostly be affecting the breaker room, where she sometimes spotted me through the side walls : I hear the "Found You" voiceline and the music and she start sprinting at me in the room despite me being completly hidden by the breaker room's pillars. Again, she doesn't spot me in the lockers, which seem to still works.
