This is the way. Uninstalling instagram, facebook, youtube, reddit, and tiktok genuinely worked for me. Otherwise it's like trying to diet when your pantry is fully stocked with every possible ultra-satisfying snack food under the sun.
I deleted the apps and then also got the mobile web/ native apps versions. it also seems the algorithm is very hamstrung given that the browser versions cannot access all of those phone permissions. now it makes it think what all data are your apps even collecting?
