This issue should be tested in 1 Android and 1 iOS device. Install the app in a device and login in a site that you can use to receive push notifications. Kill the app. Send a push notification that can be opened in the app (for example, a private message). I recommend you to test this with 2 different types of notifications, to make sure it works in more than one case. Click the notification in the device. Check that the right page is opened. Now leave the site without log out (just click switch site and click to add a site, but don't add a new one). Repeat steps 2-4. Check that the app logs you in again and the right page is opened. You can repeat steps 5-6 but using logout if you want. Please notice you will need to enter the password before the page is opened. Now repeat all the previous steps but using local notifications instead of push (using calendar reminders).
