I watch a lot of YouTube, or often have it on in the background anyway, but always on the TV and never on my phone.
To get to shorts on the TV app, I need to go out of my way to navigate to them, which I never do, so I never see them.
No.
I spend (far) too much time on devices, but this has escaped me, and it's not through any effort or resistance on my part...
1. I don't have TikTok - just never got round to it.
2. I view Instagram a few times a day but but it never seems to throw these things at me, and I don't seek them...
