So, we are looking to run Klaviyo for our client, but after launching the pop-up forms, the website started experiencing a lot of flicker. It’s not a native integration as their CMS is not supported. The devs followed this guide - https://developers.klaviyo.com/en/v1-2/docs/guide-to-integrating-a-platform-without-a-pre-built-klaviyo-integration
I’ve got zero experience with web development and have no idea where to even start looking for solutions. Never had issues like this with other clients or our own website. Any suggestions?
