Measurement Protocol implementation doesn't build Audience
We use Measurement Protocol to send hit, event, transaction data to GA.
We can see Real Time traffic, Audience, Acquisition, Behaviour and Conversion data. We collect custom dimensions, enhanced ecommerce data including product view, add to basket, refund and checkout view data.
Everything works great, except building an Audience for Remarketing. Admin > Audience Definitions > Audiences > New Audience > Define Audience
Even selecting "All Users" returns "Users over last 7 days" - 0
This despite all other metrics showing thousands of sessions, transactions, events etc.
Google support has looked into this for us but cited "Non standard implementation" as the cause i.e. we're using Measurement Protocol and not analytics.js.
So we're reaching out to the community for help. We hope someone can.
Re: Measurement Protocol implementation doesn't build Audience
Is there any part of the process that is collected from a traditional GA snippet?
I know there are limitations to Measurement Protocol and remarketing but I don't have a lot of experience with problems related to it. Specifically Google says:
"Note: For privacy reasons, data sent via the measurement protocol can be used to trigger RLSA list addition only if it is sent within 6 hours of those users' most recent visit. For addition to a display remarketing list, the data must be sent via the measurement protocol within 10 days of those users' visit."
I'm sorry I can't be of more help but if you are not tracking the user on site and then pushing back with the same client id or user id, that may be the root of your problem.
