Snapchat cache won’t clear

I tried searching everywhere how to fix but couldn’t find an answer. So ima try here. If anyone can help me it’d be appreciated❤️

When I take my snaps it’s good quality. When I send or post the snap its very pixelated and blurry. I’ve tried to clear up the cache many times but it’d go from “ clear cache: 34.33MB” to “clear cache: 22.44MB” to “clear cache: 44.55MB” I tried everything, logging in and out, deleting and redownloading, clearing convos, and clearing cache many times. It’s still blurry and nothings working.
