HI @WenzhaoTan-Chowbus , the issue will no longer exist on the version "3.0.0.beta.5" since we did some refactoring for flush and persistence. Other than that, it's in parity with 2.10.3 just without messaging and a/b testing features. If you don't use Mixpanel for messaging and a/b testing, you will get a very similar build from 3.0.0.beta.5 as the final 3.0.0. On Jan 1, 2022, 3.0.0 will be released. I'm closing this issue now, please feel free to open any issue related to 3.0.x, but we are not going to fix any issue from the legacy persistence.
