How do I go back on an iPhone 7 Plus? Don't tell me to swipe
Please help. I just switched to Apple. There is no back button on my iPhone 7+. I am within the apple called Google Authenticator. I need to go back to the main page on that app to scan a QR code, but I can't. No online advice works. Swiping left to right only opens up different apps. I need to go back WITHIN an app.
Thanks!
