For the occasional time where I’m troubleshooting something and Reddit has the only solution on an “unmoderated sub” or one with 18+ posts, I just change the “www” in the URL to “old”, and get the old, non mobile friendly UI. It lets you bypass the other app popups, etc. occasiojally when you go into a post you’re back in the new UI, and might get another pop up, but backing out or changing the url to “old” usually solves it in my occasional experience.
