All conversions showing "not set" for source/medium in Google Analytics

[Pragnesh_Patel]

Since 6th May 2025, all my conversion source/medium data is showing as “(not set)” in Google Analytics.

Any help would be appreciated!

Do Shopify has updated anything related to tracking?

Hey @Pragnesh_Patel,

Are you noticing this for app store analytics, or is this conversion traffic on a particular store?

The reason I ask is I don’t see source/medium in any of the UTM parameters here. Since this is a change you noticed, can you share a little more context on what you were getting before this?

If this is for a particular store analytics, has anything changed with google analytics of the setup of the store at all? If not, that would be supported by the google app developers

If this i

I’m tracking my Shopify apps.

[KyleG-Shopify]

Thanks. Can you share a little more about what you were seeing before? Were these provided in UTM parameters and no longer? Just so I have an idea of what you are seeing changed as I look in to this internally.

Hey Kyle, we’re facing the same issue since the start of the May and its for all our apps:

Hi Kyle,

As Pragnesh and Kanishk have also flagged, we’re seeing the same issue across several of our apps in Google Analytics. In particular, over 70% of the shopify_app_install events are now showing as (not set) —something that wasn’t happening previously.

This impacts the accuracy of our data and needs urgent attention. Would you be available for a quick call so we can walk you through our current setup?

[Pragnesh_Patel]

I have found the solution:

Step 1: Go to Analytics > Acquisition > Traffic acquisition

Step 2: Click on pencil icon on top right

Step 3: Click on “Dimensions”

Step 4: Add the “First user source / medium” and make it default(I have already added)

Result:

We are having the same issue and I shared details here. All our data for shopify_app_install event is now looks Unassigned (not set)

[Bug] shopify_app_install event stopped sending attribution data to GA4

Shopify is using the GA4 Measurement Protocol to send shopify_app_install events. This problem occurs because ga_session_id, which is being sent to GA4 Measurement Protocol, is not the same as the user session ID. I recorded a video to show this problem. I also previously shared my findings in this Twitter thread. https://x.com/faridmovsumov/status/1921207830838755662

Hi all! Just following up that our team is looking in to this and working on a resolution. I’ll update here again once it’s resolved.

[Pragnesh_Patel]

Awesome! Thanks for your support! Looking forward to your updates.

Hi! Any update on this? Sorry June data is also getting skewed

[KyleG-Shopify]

Yes. The fix has been implemented so you should start to see the proper data going through to Google Analytics over the next day or so.

Thanks for checking in

If not, let me know!

[Pragnesh_Patel]

That’s great!

Thank you so much for your support!

Currently showing few installs in “direct” source by session:

Let’s wait for day for proper data.

Again thanks for resolving the issue & I really appreciate your efforts.
