Hi,
We are finding that marketing cloud id is not being set for certain pages - we rely on this for Heartbeat reporting, so we are losing out on a lot of video reporting (interestingly, the issue seems to be most pronounced on mobile safari iphone when I look at the data).
In doing some digging, I found that yes, we are using an older version of the Visitor API that sets the loadTimeout to 500ms. Looking at more recent documentation, the default now seems to be 30,000ms. That is quite a big change.
Would you expect that changing the loadTimeout with the current version of the Visitor API would resolve our issue (at least on the scale of recovering 70-80%) of our numbers. Right now, mobile safaris video views have pretty much flatlined.
The long-term solution is of course to be update all libraries, but we are looking to implement a quick patch as this is a live issue.
Thanks.
