Library Version

1.4.0

React Native Version

0.81.5

React Version

19.1.0

Expo Version

54.0.34

Minimal Reproduction

1. Expo router navigation from default app/ to index.js.
2. index.js will be the entry point o the app with the following code for initialising the voltaListeners if Headless is detected from LiveActivity.
3. Sometimes, when multiple LiveActivities are triggered the app wasn't correctly initialised in the background. (User is on the Login Screen instead of logged In Home Screen)

import { headless } from './src/constants/isHeadless'
import './firebaseBackground'

console.log('[index.js] isHeadless:', headless)

if (headless) {
  addVoltraListener('activityTokenReceived', ({ activityName }) => {

      registerTemperatureActivityId(activityName)
    } else if (activityName.toLowerCase().includes('alarm')) {
      registerAlarmActivityId(activityName)
    }
  })

  addVoltraListener('interaction', (event) => {

    if (id.includes('dismiss') && parseAlarmDismissSide(id)) {
