Can't change workspace with touchpad anymore?

Hello, sorry if it’s a bit of a noob topic but, last night I could change workspace using four fingers on my touchpad and swiping, but now, after an OS update had occurred, I can’t. How can I fix this? It was really intuitive to use. I’m working on an Acer Aspire A715-71G.

Tried a clean reinstalling of PureOS and got it to work again, surely I messed up some config files and broke it.
