Conversion Tracking Pixel issues

We are currently facing an issue with our event tracking pixel for NewsBreak advertisers on Shopify websites, and we’d like some assistance or insights from the community. We have created the instructions here, which we pulled from the OpenPixel GitHub repository. The problem we’re encountering is that we need help to track all conversions on iOS devices. We would like to know if anyone else has experienced a similar issue and if you have any suggestions for troubleshooting or resolving it.

Although some conversions are being tracked, not all of them are captured properly. In some cases, our clients have tried using a postback solution, but they face the same problem of only tracking some conversions, not all. To be clear, this ONLY happens for shopify hosted websites. We would greatly appreciate your input if you’ve encountered this issue or have any insights to share.
