We are in an urban area with 5 bars and 5G on the phone. We are also connected to wifi. All configurations and settings on phone are optimized for use with Zeffy. We still have issues with Zeffy tap-to-pay not always working. Sometimes it just spins for minutes. Customers and our volunteers get frustrated. We restart the app and do all other recommended troubleshooting. We even upgraded to a new 2026 phone model. The problem persists. There should be a way to store the credit card info until Zeffy comes back online and can be charged.
