If Union Bank Mobile Banking stops working after the latest iOS update, try these first: Restart your iPhone, then open the app again after you've forced-quit it (swiped it away).
Next, go to the App Store and see if there is an update for Union Bank's app. Usually, installing the most recent version makes apps compatible again after a big iOS update.
If updating doesn't help, delete the app and then restart it. This gets rid of any old data or cache that might not work with the new operating system.
Also, make sure that your internet connection (Wi-Fi or cellular) is secure and that your iPhone's storage isn't full. Banking apps may freeze or not load if your network or storage isn't good.
If none of these work, you can file a report with Xolvie to try to get things fixed.
