Hi,our team is utilizing GrowthBook for A/B testing on our Android application, which serves a global user base from different countries.
A specific experiment, set Android device ID as the assignment attribute with a 50% traffic allocation.
We observed a discrepancy on the first day of the experiment: only 8% of eligible devices were included, rather than the expected 50%.
on the First day 8% users were included
on the second day 12% users were included
on the third day 17% users were included
this data comes from Firebase user event tracking data
anybody know if it is normal? How can we include 50% of users for the experiment as soon as possible
We kindly request some assistance in diagnosing this issue.
Thanks very much!
