TURN OFF TAP TO PAY FEATURE

From my experience, I attempted all the suggested solutions in this community to connect my Square Card reader, but unfortunately, none of them worked for me. Surprisingly, customer service advised me to replace my reader even though it was functioning perfectly fine just yesterday.

However, I was able to successfully connect my Square reader after turning off the tap to pay feature.

Based on my observations, I believe there may be a conflict between the One UI and Square App.

For context, I am using a Samsung Galaxy S20 and running Square App version 6.16 on Samsung One UI version 5.1. and Developer option is ON.

Using Samsung S20 and Square. Card reader stopped working today. turned off "Tap to Pay" feature and the card reader started working again. It was working even with the error message showing but today Square said it was updating and my card reader stopped working. There is definitely an issue with "Tap to Pay" feature being turned on. Using Square 6.2.1
