How do I use YNAB with multiple currencies?
YNAB can handle virtually any single foreign currency, but it does not support multiple currencies in a single budget file. We have our eyes on this functionality for a future release, but do not have a specific date set.One workaround is to set up a budget file for each currency. While this isn’t as elegant as having it all in one file, it’s the best we have to offer at this point.
