Sideload or jailbreak depending on device

Install Vinegar: https://apps.apple.com/ca/app/vinegar-tube-cleaner/id1591303229

Pulls the actual video file from YT, stripping ads, overlays, and anything else YT shoves into them. Literally a game changer on Apple devices.

use sideloadly https://sideloadly.io/ and download the ipa from here: https://github.com/arichorn/uYouPlusExtra once you set it up all you need is to literally open sideloadly once a week on your pc/mac and hit refresh while the iphone/ipad is connected to the same wifi. apple doesnt let you add apps for longer than week unless you pay to be a developer so a 30second job to refresh the app and ur done.
