Signed In to Multiple Devices
Accessing Cash App on multiple devices is the main reason account sign-in fails. Multi-device sign-in means you are signing in to Cash App simultaneously on different devices with only one account, against Cash App policies.
While you can sign in to Cash App on different devices such as your desktop, phone, or even a friend’s mobile device, you can only sign in on one device at a time.
Running Background Apps
Apps running in the background may conflict with Cash App. For example, the apps may hide your location data, such as VPN. As a result, your sign-in may be considered untrustworthy by the app, and your payment failed for your protection.
In addition, some apps may not be compatible with Cash App when run simultaneously.
iOS System Glitch
Although it’s less common, your iPhone may crash and have glitches. Have your device updated to the latest iOS version because some updates contain bug fixes.
You can also check online forums to see if other iPhone users are experiencing the same errors with the current iOS version.
