This is my first question in StackOverflow. I´m sure it will be useful and I hope you can help me!
This is my problem: In the context of Firebase data model, importing a datasource from Data Studio GA4 I found that both for Android and iOS there are lot of purchase events that doesn´t display information about the currency parameter (it shows as not set). Data Studio output
In order to analyze this issue, we went to BigQuery so we can could take a look to the raw data. There, we found that in the iOS case the biggest problem is that the revenue parameter of the purchase event is being sent as string, when the official documentations indicates that it should be sent as double_value.
But for the Android cases we are still confused, since we can´t find in BigQuery any case in which the revenue parameter is being implemented as string nor it doesn´t have the currency parameter set. So my specific question is: is there a possibility that the BigQuery export doesn´t include the purchase events that doesn´t have the currency parameter implemented? Or do you have any other suggestion on what might be happening?
Thanks in advance!
