Roblox first session: diagnosis plan

Six actions in priority order

A funnel locates loss, first-session retention shows the pace of exit, and D1 measures return. These metrics answer different questions and mature on different schedules.

Events should confirm completion on the server: a click, purchase attempt, or task start is not success. Before release, exercise the normal path, retry, reconnect, and failure in View Events. If the step schema changes, mark its version boundary; otherwise a chart movement may reflect measurement rather than player behavior.

After the repair, verify the target step and absence of new errors before waiting for D1 or D7. If acquisition source changed with the build, preserve both factors as alternative explanations.

1. Define the job of the first session in one sentence.
2. Run an observed playtest without coaching.
3. Log only successfully completed server funnel steps.
4. Connect the loss shape to a possible mechanism.
5. Compare equally mature cohorts and sources.
6. Fix one confirmed blocker and record the next question.
