How to uninstall Ratio? Squeeze Pixel 2 XL

I decided to try Ratio on my Google Pixel 2 XL, but I realized that the function ‘Squeeze’ that has this phone is not longer working.
So I tried to uninstalled properly, and I couldn’t do it, so I just unistalled like if it was a regular app, but the function is still gone.
Can anyone help me?
I would like to try it again if it doesn’t comes at a trade off of functionality
