Analytics 4 Traffic Vs Universal Analytics

[BIABAJay]

I currently have Google Universal Analytics setup (Online Store -> Preferences). A few days ago, I setup Google Analytics 4 using the this guide:

https://help.shopify.com/en/manual/reports-and-analytics/google-analytics/migrating-to-google-analyt...

It's setup via the Google App. 

The traffic  over the past two days isn't matching up at all for some reason. Analytics 4 is recording 1/4 the traffic that Universal Analytics is. 

Any ideas why this may be happening?
