A. Force close the app and reopen it. On your iPhone, swipe up from the bottom of the screen (or double-click the Home button on older models) to view the app switcher. Find the RTSH TANI app and swipe it up to close it. Then, reopen the app from your home screen.
B. Restart your iPhone. Sometimes, a simple restart can resolve app issues. Press and hold the power button until you see the slider, then slide to power off. Wait a few seconds, then turn your iPhone back on.
