OneDrive not syncing?

I just got one of those popups saying I was running low on OneDrive space. 91g used of 100g.

I deleted a bunch of stuff from my phone's photos/gallery.

Device care now shows 44.19g (34% used space of 128G). 39g of which are accounted for by apps and system files.

But OneDrive still shows 91g used of 100g.

Am I not giving OneDrive enough time to do it's job? Is there a way to initiate a manual sync?

Goto ondrive on the web and empty the bin

First thing I did. There was nothing in there.
