hi @tusharvohracoder , the issue will no longer exist on the version "3.0.0.beta.5" since it is using SQLite for persistence. 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 file persistence.
