Not 100% sure it’s because of the new app, but I get a lot more ghost travel (like one data point at my current location) after start use with the new app
(The bus is a false data point)
It looks like a later data point is being merged into an earlier timeline, because if I sort out the wrong data point it gets correctly reassigned to the correct later timeline entry
The longer day overview correctly identifies this as a 19 minute drive
