Hello,
Glad you resolved the issue, but this has probably nothing to do with versions.
You should have the latest versions installed. Latest wallets version is currently 5.0.4, and latest fiat adapter version is 0.5.1-beta.
Whether you see the fiat currencies listed depends on whether the Exchange Rates subsystem has had a chance to retrieve the latest data from fixer.io.
So, my recommendation is that you check to see that you have the latest versions installed in all components, then go to “Wallets” -> “Exchange Rates” and hit the button “Clear/refresh data now”. This will force the plugin to pull the data immediately.
with regards
