If you don't mind seeing the desktop interface, prepend "old" to the domain on any reddit page (i.e. change the domain to old.reddit.com) to bring up the legacy interface. Loads quick and works fine on mobile if you don't mind zooming.
That said, it's ridiculous that this is necessary.
The other day I tried to view a subreddit in Safari. It was literally impossible, it was claimed to be only available in the app.
