There's definitely a few exceptions, though they're mostly minor annoyances or caused by apps that expect you to be permanently online with a good connection. The most frequent one I've seen on Android is swiping down while (almost) at the top, and the entire view refreshes. This is mostly in the browser, which simply reloads the page after a few seconds (resetting any text fields you may have modified) and in this case the gesture can be cancelled by reversing it. Unfortunately, if the browser or app has been open for a long time (say, I've left a news app open for three days), the view can be quite different once it finishes reloading, and can be impossible to get back to where I was previously. Lazy-loading content can also cause issues when offline if the placeholders don't update (Materialistic, the app I'm using now, has both these issues). Occasionally I'll find an app that likes to do annoying bouncy things with the view when overscrolling the bottom of a list, but that's fortunately rare.
