UTM Parameters Being Stripped From URL - Flex Theme by Out Of The Sandbox

[avcanthony]

Hi all, 

I'm in need of serious help. I've recently been informed by my support rep at Cometly that my ad tracking has catastrophically failed over the past 3 days because my theme is stripping my UTM parameters. 

The theme is Flex by Out Of The Sandbox, and I recently updated it to the most recent theme version, version 3.2.0. I want to note that I was not having issues with UTMs being stripped prior to updating my theme. However, I think I may have found what's causing the issue. In the theme changelog, they state as part of their 3.2.0 update for Flex: 

• "Updated product page URL to include variant ID when switching variants"

The problem with this is that anytime I try to add a UTM parameter to the end of this URL: https://trynutriskin.com/products/nutriskin%E2%84%A2-microcurrent-cellulite-facial-slimmer?variant=4... , the UTM parameter is stripped, and thus, my ads do not correctly track conversions. It's like the variant ID is taking priority over any other UTMs I add. 

Here is also a 1 minute video from Cometly explaining to me what is going on and showing the UTM being stripped in real time: https://share.getcloudapp.com/NQul4e4E 

I am not a coder by any means. I can barely grasp what's going on. But I've reached out to the support team with Out Of The Sandbox, but haven't heard back. I even paid for their priority support, and didn't hear anything back either. 

Does anyone know how to fix this? I notice that there's not many resources on this at all. Any/all advice is appreciated!

I have been having the same issue since upgrading to Flex 3.2+.  Did you figure it out?

In case anyone still needs this, contact OOTS/Pixel Union support.  They are aware of the issue and was able to fix it on my theme fairly quickly.
