Some users have stated that blocking the user will delete the corresponding transaction. Unfortunately, based on our tests in June of 2022, this doesn't work. However, if you'd like to try it, here are the steps: 1. Open Venmo and visit your friends' profile. 2. Tap on the three dots in the upper right corner. 3. Tap Block. You can follow these same steps to unblock the user. Hopefully your transaction will disappear, but if it doesn't, your only option is to follow the steps above and make your transactions private.
