Known issues
Users occasionally experience long wait times during peak hours or when dealing with complex issues. To mitigate this, it is advisable to use the in-app chat for faster responses or call during off-peak hours. Additionally, certain account changes, such as updating phone numbers or email addresses, cannot be completed over the phone and must be done directly in the Monzo app. This limitation is frequently encountered, so having the app installed and ready is beneficial. For urgent issues, the 24/7 in-app chat is the most efficient option.
