On Amazon device OneSignal messages stop showing after the device is restarted or randomly a couple of minutes after the app is closed

[GinsGins]

Description:

• On Amazon device the one signal messages stop showing after the device is restarted or randomly a couple of minutes after the app is closed.

Environment

1. I am using 2.13.6 version of oneSignal unity SDK
2. This issue occurs only in Amazon Fire OS (I am testing on Fire HD 8 Plus - 10th generation - Fire OS 7.3.2.2)

Steps to Reproduce Issue:

1. Import one signal unity sdk 2.13.6
2. Set up one signal for Amazon devices
3. Open App (Device registers and one signal messages work)
4. Restart device
5. Don't open the app
6. Try sending push notification to the device
7. That is when the error occurs

Anything else:

My investigation:
I found this similar issue in your android sdk:
OneSignal/OneSignal-Android-SDK#890
which was fixed for your android sdk with this commit (commit that added support for FireOS 7):
OneSignal/OneSignal-Android-SDK#1184
which if i understand implements the adm message handler job base,
In the unity sdk i didn't see those changes, could that be the case, that support for fire OS 7 was not yet added in your unity SDK?

We see the same crashes in our Firebase Crashlytics in Google Play build on Fire HD 8, Fire HD 8 Plus, Fire HD 10 (2019, 2021).
OneSignal SDK: 3.0.2
Unity: 2020.3.36f1

@GinsGins The OneSignal SDK wasn't compatible with FireOS 7 until OneSignal-Unity-SDK 3.0.0.

• For reference this SDK uses OneSignal-Android-SDK and it was added in OneSignal-Android-SDK 4.0.0-beta2

@gadzilka Do you see this issue still if you update to the latest OneSignal-Unity-SDK 3.x.x SDK or 5.x.x SDK? if you do let us know what logcat entries you get, such as what was posted above.
