A Fortune investigation shows that an iPhone enabled with Crystal — the top paid iOS app right now – is unable to fully render the e-commerce sites of many major retailers, including Walmart, Sears and Lululemon.

I’ve noticed similar problems on a handful of websites while browsing with content blockers enabled. Luckily it’s easy enough to reload the webpage without them — tap and hold the reload button and choose “Reload Without Content Blockers” — but it’s unlikely that the average user is going to know how to do that. How many potential customers are just going to leave and purchase elsewhere when they encounter problems like this because “the site doesn’t work?”

I guess online publishers aren’t the only ones who could be hurt by ad blockers.
