I recently implemented AA tracking for our site. We already have GA tracking in place so over the past week, I've been monitoring the discrepancies in data on the two platforms to see if AA is tracking data accurately. For the most part AA tracking is in place. However, Firefox browser on Desktop is tracking much lesser visits compared to what I am seeing in GA. The discrepancy is almost 500% which obviously I can't ignore. Further deep dive suggests that particularly browser version 63 is showing the highest discrepancy.
I tested the firefox 63 version on broswerstack and did some tests to see if the sessions are being recorded and if all tags are firing. I can confirm that all the tags are firing as expected and I was able to locate my session in AA. However, there are a lot more sessions that are not being recorded in AA based on the numbers I am seeing. Did anyone have any such issue during their implementation? Any ideas on how to tackle this problem? Thank you so much!
