Hey 👋🏿 ! We’ve been using GrowthBook for a while now, and for the first time we’re faced with a SRM on one of our A/B test, we’ve checked the implementation, and don’t figure out what’s wrong.
The help message attached to it says we should check: • Bucketing • Execution • Analysis • Interference
but I believe we don’t really have a hand on bucketing since GB does it by itself

Hi Gania - it can happen if you changed the split percentage
how many users are in your experiment currently?

We've changed the split at the beginning of the week
Can we set the beginning of the experiment in the board?

we actually found the answer
we were looking at the SQL queries, and weren’t sure where to choose the start date
thank you for hinting me the split % change
😃

cool
glad I could help
if you change the overall exposure, you don’t have to change the split to ramp up the experiment, and you wont get multiple exposure problems or SRM problems
