The docs and blogs emphasize that Mixpanel invests heavily in backend performance and interactive speeds, but they don’t provide specific troubleshooting steps for front‑end lag on a single account or browser. [Product analytics you can afford]
Because of that, I don’t have official guidance on browser-specific fixes (e.g., clearing cache, extensions, etc.) in the knowledge sources.
Given your description (multi‑second delay on basic UI actions), this is not expected behavior and is best handled as a Support case so they can:
Check if your project is hitting any internal limits (e.g., hot shards, extreme cardinality) that might slow queries. [Hot shard limits]
Verify whether there’s any ongoing incident affecting your region or org.
Look at your specific reports and environment.
You can open a ticket from within Mixpanel via Help → Contact Support, or via https://mixpanel.com/get-support, and describe:
That the UI itself is lagging (not just query results),
Rough time window and your region,
Whether it happens across all reports/browsers or only some.
If you’d like, paste an example of a “slow” report configuration (events, breakdowns, date range) and I can help you simplify it using the documented best practices.
