is installationId consistent when updating the app / sdk?

I need to get a persistent device ID when the app is installed.
It’s ok if it changes when the app is uninstall / reinstall but I want it do be persistent when the user update the app, even if the expo SDK has been updated in this update.
Is Expo.Constants.installationId guarantie this?


Hey @alanlanglois,

The installationId value should remain consistent upon SDK upgrades, but as you mentioned it will change upon installing and reinstalling.
