react native navigation deep link to a specific tab

Question

this is my first question on here, and maybe I am missing something simple but I cannot find my answer anywhere.

My project uses redux and has several "root" changes with both tabBasedApps and singleScreenApps. When using the drawer to deep link to a specific tab, if you are in the current tabBasedApp root, it will correctly go to the right tab with what I am using (below). But if you are in a different root of the application (tabs or single app) and have to change the root and then try to link to the correct tab - it doesn't work. It seems to skip over any navigator method and just print the console logs. So trying to get to "friends" from a different root just stops at "profile". I'm guessing it is a problem with the roots changing but I don't know.

Below is part of the event listener for the deep link. "appRoot" and "navigator" isn't "this.props..." because I am passing the nav event into a separate handler to reduce code duplication - it works with everything else I have tested, just not this (which I am assuming is not the handlers fault but I could be wrong).

I get a warning on iOS: Possible Unhandled Promise Rejection (id:0) Error: could not find UITabBarController Nothing on Android, it just doesn't work.

    if(event.type === 'DeepLink') {
        console.log('deeplink from nav');
        const parts = event.link.split('/');

        switch(parts[0]) {
            case 'profile':
                appRoot('profile');

                if(parts[1] === 'profile') {
                    navigator.toggleDrawer({
                        side: 'left',
                        animated: true,
                    });
                    navigator.switchToTab({
                        tabIndex: 0
                    });
                }

                if(parts[1] === 'friends'){
                    navigator.toggleDrawer({
                        side: 'left',
                        animated: true,
                    });
                    navigator.switchToTab({
                        tabIndex: 1,
                    });
                }
                break;

Steps to Reproduce: Build project using the redux example to be able to switch between roots. Have drawer with a button to go to a specific tab in one of the root tabBasedApps Handle the deep link from the drawer
