Has anyone else had the Ui updates cause display issues this is the second time now for me . The need to beta test updates on all phones before they roll it out.
Temporarily until resolved, you should be able to access CBA using your browser. Something to try, Go to Settings, scroll to Apps, find CBA app, clear cache in app, ALSO clear cache in Google Play Services as it contains some CBA settings. Uninstall app, restart phone. Reinstall app and you may have to contact CBA (or using browser?) To reset CBA settings.
