Swipe left vs. swipe to the left

[Miss Mae]

I am using an app that says "swipe left to reveal the comments." And so I tried to do the action the first time I had used it--sweeping my finger from the left side to the right side of my smartphone. But the comment page/section didn't appear. The other night, though, I accidentally moved my finger from the right side of my smartphone to the left side and the comment page/section appeared! So, I've come to think that the developers of the app should've put "swipe to the left to reveal the comments" instead. Right?

Not all those who venture into the Internet are well-versed in English, so it's not surprising that even if they are computer-savvy, they sometimes could make egregious or honest mistakes in reckoning with or describing directions, magnitudes, generally accepted norms, and arbitrary language-specific standards. We just have to be particularly careful with apps developed by nonnative-English-speaking techies regardless of their country of origin. If in doubt about an instruction that looks, sounds, and behaves dubiously, ask for confirmation first before clicking that "Yes" or "No" button.

Thank you for your reply!

Can you advise the app's developers about their honest mistake then? The app has many users, seemingly targeting  entry-level professionals.
