An update, quite literally...
Magic Earth routed me onto a toll road in Portugal yesterday, namely the A25 at Aveiro. This concerned me so I checked the OSM mapping later and found that the A25 was now noted as having no tolls.
It occurred to me that this might be an error so I posted about this on the OSM Community forum. Very quickly I was advised that the toll status had been changed recently, and another contributor cited an item on the web about the Portuguese government removing tolls from some roads with effect 1 January.
Unfortunately the government has not updated or removed the signs.
This shows how quickly map changes can be effected and the relatively short timescale for these changes to be applied to the app.
