Webpixel extension not firing on some stores

[slashcart]

I have a shopify app that uses webpixels extension but for some stores but working as expected for most of the stores. Can anyone help me what can be the issue?

[Liam]

Are there any commonalities for stores where the pixels are not working as expected?
