The game review post-game rating is meanngless. Don’t pay any attention to it. If you want to know your “true” playing level, play in OTB tournaments with classical time controls.
i looked at some of your most recent losses. You are not close to being 1900. In one game, you did not defend against a mate in 1. We expect that from beginners.
OTB, I don’t think you would be 1600. You miss threatened pieces, do not win after your opponent has given you decisive amounts of material, and make serious opening mistakes—even in openings that you play repeatedly. My guess is that your actual level is around 1200-1300. That is about a rating class below the average club player.
There is no need to look for conspiracies to explain your rating stagnation. Better to try to improve your game.

YESS, I sometimes play at a 1900 level but my rating is 700 it's dumb, so I'm put against the best 700's on the website, it's pointless and I'm stuck...
Don't listen to game review it's dumb plus yes even 600s can beat 1900s rarely everyone gets tunnel vision it doesn't matter the level you all thinking your better than you are is actually pretty normal for beginners
