Photostream not syncing on MacBook

I have an iPhone XR and a MacBook Air.

Both devices have photo stream switched on and both are logged into the same apple ID

When I take a photo on my phone it immediately transfers it to an album called Photostream. However this does not then appear on my MacBook

I have tried this several times and have waited up to half a day, and nothing appears on my Macbook

When I go into setting on the MacBook turn off photo stream and then turn it back on a few seconds later, the photos appear

Is there something im missing ? Is there a setting that needs to be on ?

Very confused and any help would be appreciated
