Search bar not recognizing apostrophes

Hi!
I noticed that when searching for anything that includes an apostrophe, no results show up.
For example, if I search for “Amy’s Kitchen”, nothing shows up. If I search for “Amy Kitchen”, the results show up correctly, however. The problem is that readers are likely to search with the ‘ and I’ve received negative feedback from people saying they weren’t able to find the articles they were looking for.
I tried updating plugins & themes, changing the header etc. Interestingly, this error only occurs on desktop views and not on mobile views.
Does anyone know how to fix this? The site is https://bestofvegan.com

Thank you!
