What to Do When an Update Kills Your Retention
Before you roll back or rewrite, find out whether the update was the cause.
Retention dropped after you shipped. The temptation is to roll back, or to ship a fix for what you assume went wrong. A quick wrong guess costs more than a slow correct one, so spend the first hours establishing what actually happened.
Step 1: confirm the drop is real
- Check the sample. Small cohorts swing a lot; see the rule on error in Why High CTR Doesn’t Always Mean Good Roblox Ads.
- Check that you are comparing the right days. Weekday and weekend patterns differ.
- Check that the metric itself did not change, for example in how it is logged.
Step 2: compare cohorts
- Players who joined before the update and those who joined after.
- Players who saw the changed feature and those who did not.
- New players versus veterans.
- By traffic source, device and country.
If only one group dropped, the cause is probably tied to that group. If everything fell evenly, look outside the update.
Step 3: check external factors
- A change in paid traffic or targeting.
- A traffic source that ended or a creator mention that faded.
- School holidays, seasonal demand or a competing release.
- Platform-level changes or outages.
- A crash or performance regression that began with the release.
Step 4: isolate what changed
List every change in the release, including the small ones. Then ask which could plausibly affect the group that dropped. Check error logs and the first-session funnel. A bug in a basic step, such as a broken button, is often found by simply playing the build as a new player.
Step 5: choose a response
| Option | Choose it when | Risk |
|---|---|---|
| Roll back | The cause is clear and tied to the release, and the old version is safe to restore | Losing wanted changes and any data created since |
| Hotfix | A specific bug or setting is the cause | Rushed code introduces new issues |
| Follow-up update | The design choice caused it and needs rethinking | Slower, the drop continues meanwhile |
Rolling back is not automatically safe. If players have progressed on the new version, check whether their data survives the return.
Step 6: tell players
Say what you saw, what you are doing and roughly when. Do not blame players or hide it. Do not promise fixes you have not tested. Update again when you have results.
Step 7: recovery plan
- Write the hypothesis and the metric that will confirm it.
- Set a date to review.
- Change as few things as possible.
- Record what you learned in your update log.
Avoid the panic rewrite
A rewrite is a large new release with the same uncertainty as the one that failed. Fix what the evidence points to, in small steps, and measure after each.
