[question]: Questions about in app message deliveries

[parvez-keeptruckin]

How can we help?

Using OneSignal iOS SDK v3.11.2. We are setting externalUserId for a user when logged in and removing it on logout. We are using MixPanel - OneSignal integration to consume MixPanel cohorts in OneSignal as user segment. The in app message is supposed to show only once when a given trigger and user segment condition matches. Sometimes it happens that even when a given in app message is supposed to show only once, it is repeatedly appearing whenever app is run.

Let's suppose user A login on an iOS device and able to see a show only once in app message. Will this message appear again when same user login on an Android device ? Will message come again when uninstalling the app and reinstall it again and login with same user ? Will in app message shows up again when re-export the cohort to OneSignal ?

Ideally for a same user who already received a given in app message on one device should not receive it on another device.

What's the behaviour on Android device with regard to all above questions ?

@parvez-keeptruckin Unfortunately currently our SDK will still display the IAM once per device even if they have the same external id. This is a known issue with external id and we are working on overhauling our behavior around "users" to behave in the way you expect.

We have captured this enhancement request internally and will close this issue.
