We prefer using the legacy tool for almost everything (except for faster calculation of funnels in V3), we want to keep the legacy tool open all the time.

However, when we switch to legacy tool, it forces it back to the new version usually after a few minutes of idle time.

Also, the game data loading time often slows down incredibly when using the legacy tool (not for the new version). This wasn't the case in the past with the old version. Say we switch from Engagement tab to Overview tab in Legacy tool and suddenly it just hangs for like minutes and then ends up redirecting to new version. It creates so much work for us to keep switching back to legacy tool and waiting for data to load, it's like some casino slot game where you never know if you'll get the data or you'll have to start over again and again.

Not to mention the 'legacy tool' option is hidden so that we haven't even noticed it for months. The 'legacy tool' switch button should be available at top level all the time.

We shouldn't be forced to use a beta product until all the important functionalities that worked before are implemented and bug free. The current V3 new version feels like it should still be beta, still too buggy and it's missing data and features that we had in the old version. We're used to the UI of the old version, where to find what.
