Stape Gateway on Shopify affecting sessions in GA4

Ever since I implemented Stape Gateway on the acerstore.cl site, the total sessions that GA4 is measuring have been cut in half. If I compare the sessions that Shopify gave me before the implementation with GA4, they were very similar, but after implementing it, GA4 gives me half the sessions that Shopify does. What could be the reason for this? Could something be misconfigured?

@Cristian_de_la_Maza Since the gateway is a completely automated system where the person only has to enter their credentials, I can tell you that this is unlikely to be the problem.

I have checked your website and I can see that the events were successfully captured and going out to your Stape Gateway. I could see no apparent issues with your tracking setup, everything works as it should.

Thank you for your responses. I actually discovered that there was an error with the pageview event implementation in Google Tag Manager, as it wasn’t firing. I had excluded it in the GA4 Google tag, and the pageview tag wasn’t working. What I did was remove the exclusion from the Google tag. Any recommendations on this? Does anyone have an updated guide to implement Stape Gateway on a Shopify store using the Shopify app and Tag Manager?

Setup for Shopify is no different from other platforms. Stape Gateway simply redirects your GTM configured client-side tracking through the server. So you just need to have a GA4 setup in GTM with all the events you need + Google ADS conversions if you use them. When you connect Stape Gateway according to stanadrta instructions - all this will become server-side.
