- Place the cursor in the ‘Search’ input field.

Custom alerts can be created with zero-value decimal price targets (0.0, 0.00, etc.)

During our testing, we identified a few issues concerning the stability and consistency of the Coinbase app’s performance. These included endless loading spinners, generic error messages, and, at times, difficulty completing desired actions. To enhance user trust and provide a smoother UX, I recommend comprehensive testing to improve error handling, loading states, and validation consistency.
