Sadly I had to install Adobe Reader on my father PC again after he had documents* with formulas. Chrome would calculate the numbers wrong. Everything was off by 10.

*To get reimburses from a union or something.

If you occasionally need Adobe Reader/Acrobat exclusive features but don't want to install, you can use the free online version of Acrobat. It's pretty decent though it doesn't have all the features:

I recently had issues with macOS‘ Preview.app and formulas. It’s a nice feature, but probably not widely supported.

Whoa, I had no idea PDFs can have formulas.
