Sentry.init({
      sampleRate: sampleRate?.errorSampleRate
        ? sampleRate?.errorSampleRate
        : 0.5, //We fetch the sample rate on app launch/initialization we have a 50% sample rate as a fallback in the event we fail to fetch or device is offline

I have following issue:

Tried calling Sentry.lastEventId() on the main screen of our app after a crash had happened and it returned undefined. Looks like event Id is not persisted?

Steps to reproduce:

• Call nativeCrash() from "@sentry/react-native"
• On app relaunch call Sentry.lastEventId() and inspect value returned.

Actual result:

undefined

Expected result:

Some sort of Id

Sentry.lastEventId() isn't persisted for hard crashes, you are correct. IIRC lastEventId is persisted on Android and iOS, maybe we can leverage the RN bits for that, I'll check it.

Hi, do you have an update on this feature? I find it surprising that we can't tell if the application crashed in the previous session on react-native

@ludwig-pro Hi, thanks for your interest, we want to do this, but there is no closer plan yet.
