Old Reddit doesn't work well on mobile devices at all. While it can scale the user interface, it's designed with a mouse in mind, making everything appear too small. I like using Old Reddit on desktop, but it's not user-friendly on mobile. For example, on HN (Hacker News), it's simpler; there are no images or different-sized icons. Even here sometimes struggle to tap the right links or flags, and I have to manually go to the settings to undo it. I'd prefer this over a poorly optimized mobile UI. However, optimizing the mobile web page would solve these problems.
Rotate your device to landscape and it's fine. I guess part of the problem is sites training everyone not to do that. (Quora's expert designers will happily throw content into the void of the iPhone's notch on landscape, inventing a problem that didn't exist in older designs, despite them having been created before the notch ever came out.)
Rotate isn't good solution it like saying not open site in full screen open it in half screen o is similar to mobile, I use mobile on the go and can't acomodate bad design whit behavior changes you need too change the design, so people can use it whiout needing to change everything.
