# Troubleshooting

### Unable to update exchange rate

Many a time, you click on the Sync icon in order to force an instant update for the current currency list, you may encounter this error notice.

This issue is most often caused by unavailable exchange rates for the selected currency pair. 

For instance, if you want to convert USD to BTC, but this currency pair is not available in the [current Finance API](https://docs.yaycommerce.com/yaycurrency/configurations/settings), then its exchange rate can't be automatically retrieved.

In this case, you have to use manual exchange rate. Here are the steps to fix this:

1. From the dropdown of Rate type, choose **Fixed** to switch from Auto to Manual mode.
2. Then, you will be able to manually enter the current rate for this currency pair. Eg, 0.000033 for USD-BTC.
