I can’t get rid of it, it’s obnoxious. I’ve tried filtering the element with my adblocker but it keeps reappearing. As much as I find Reddit useful (unfortunately), especially for information and discussion relating to my country, I will never install their proprietary garbage app on my phone just to use their website.
Oh well. I’ve used the Internet before Reddit existed, I’m sure I can get used to doing so again.
Settings -> Preferences -> Default to old Reddit -> turn it on
It’s a per-device setting, so this needs to be done on the phone. But there’s no such message anymore if you do that.
