While Firebase has many strengths, I find it notably challenging, if not impossible, to create diagrams for tracking KPIs directly in the platform. The need to constantly reapply filters is not the most efficient way to monitor important metrics. Furthermore, I'm somewhat skeptical about the accuracy of the tracking data, which sometimes seems less precise than expected.
Despite these issues, I must commend the excellent features like Authentication and Firestore that Firebase provides. These tools are fantastic and greatly simplify many aspects of app development and data handling. They certainly add significant value to the platform and make it a powerful tool for developers. I look forward to seeing how Firebase evolves to address these feedback points in future updates.
