Through the Cash App server is not down, if you are finding out the reasons why Cash App Won't Let Me Add Cash, you don’t need to worry as it can also happen due to the low funds available in your account. So, you should first check the balance and then initiate the payment from your account.
Check Your Internet Connection
One of the most common Cash App problems is a loading screen loop. Rather than opening to the screen you expect, Cash App will get stuck on the initial loading screen. This is often caused because your internet connection isn’t steady; your phone’s signal might be too weak, or your Wi-Fi connection isn’t as solid as it needs to be. Perform a speed test or turn off your Wi-Fi and try again.
Update Cash App
One of the main causes of Cash App issues is an out-of-date app. It’s also one of the easiest fixes. Make sure your Cash App is up to date on your Android or iOS device through the app store.
Clear Your Cash App Data
Clearing your app data can resolve a lot of problems, especially if Cash App is crashing. You can do this easily by deleting and reinstalling the app (which will also serve as a troubleshooting step in and of itself.)
