Google Maps not showing timeline even though Location History is ON

Hello all,

I have an iPhone 6s on ios11.

I recently enabled Location History on Google Maps because I wanted to utilize the Timeline feature. I enabled it within the app and I also changed the setting to "Always" in Location Services within the iPhone settings themselves.

When I go to google.com/maps/timeline it tells me that Location History is On however when I try to view the timeline on the days since I've enabled it, it says that I have no location history.

What have I done wrong?

Any help is greatly appreciated!
