For some reason RUB currency doesn't work:(

It says "Error - expected source or destination currency not in rates file".
And indeed, there is no RUB currency in eurofxref-daily.xml file.

This is the European Bank - See here:

"Owing to current trading activity in the EUR/RUB market, the European Central Bank (ECB) is not in a position to set a reference rate that is representative of prevailing market conditions. The ECB has therefore decided to suspend its publication of a euro reference rate for the Russian rouble until further notice. The ECB last published a EUR/RUB reference rate on 1 March 2022."

Maybe you can make it work through google? It may be not that accurate, but at least it works. Thank you.

Adding a second provider isn't a small change. I am busy with my work until late June, but will have a closer look after that and see if there is anything I can do.
