Push Notification icon not coming in android version 23

I have build a restaurant app, integreted ionic push notification service and uploaded the app with targetSdk 23.
Now what happens, icon of push notification is not coming in android device >=23 and icon is coming at device <23.

i tried downgrading targetSdk to 22, its working. but i can’t upload that apk to google play store as they say that.

Keep in mind that once you publish an APK targeting API level 23 or higher, you won’t be able to submit an update targeting API level 22 or lower on any channel.

So what i can do now to upload a 22 targetSdkVersion apk on play store where my current app on play store have 23 targetSdk
