any update on the issue. I am experiencing same issue? any work around? please help

I've seen a similar issue (not sure if that was also with InAppBrowser opening the system web browser), and worked around it by using another plugin like cordova-plugin-app-launcher with the FLAG_ACTIVITY_NEW_TASK flag (for the launcher plugin that would be: cordova.plugins.launcher.launch({uri: url, flags: cordova.plugins.launcher.FLAG_ACTIVITY_NEW_TASK})).

I am facing the same issue, is there any way we can set the plugin launch mode to SingleInstance, that way it always opens up in new task instead of merging it on top of the existing activity in the same task?

Currently I had modified the source code in openExternalExcludeCurrentApp() function with this inoder to open it always in a NEW TASK:

if (hasCurrentPackage == false || targetIntents.size() == 0) {
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // added this line to explicitly open in new task
            this.cordova.getActivity().startActivity(intent);
        }

If you're using ionic deeplink with this plugin https://github.com/ionic-team/ionic-plugin-deeplinks#android-configuration, this conf in config.xml will help :

<preference name="AndroidLaunchMode" value="singleTask" />

this issue has been plaguing me for a long time. Though I am not using ionic-plugin-deeplinks, I just tried @Stephane84 idea and its still not working. This is only an issue on Android.
