I've been trying to diagnose an issue with our AppMeasurement for JS tag, where the page view doesn't actually get recorded on every page view of our site. It seems that somehow the tag sometimes hangs on the VisitorAPI.js callback.
Has anybody else experienced this? Been working hard to try and debug this, but nothing obvious at the moment.
I may have made progress on this - basically I tried breaking out the VisitorAPI part of the AppMeasurement template into a separate pre-loader extension, and this does seem to behave more predictably.
I've recently heard of other company's having this same issue, and they are not using Tealium. So initially this does not seem to be a Tealium specific issue.
We are looking into what may be causing this and will update this post when we have information.
