So I realize many of you aren't on reddit and use this instead, but wanted to share on here anyways. Tried navigating to reddit since updating to Android 12, and getting hit with this wonderful pop-up.
I'll be moving, hopefully, to LineageOS, but I won't be banming off having reddit on there either. Not a fan of their native app for behavior tracking reasons.
I think that happens only for some subreddits like r/piracy,imatotalpieceofshit etc. that they deemed 'problematic' or something so they force the app on all posts.
If you are using uBlock Origin I think this filter removes the element:
