Sorry if this is considered a low effort post but I can't find any confirmation anywhere. I had a direct ICE ticket for a trip from Stuttgart to Frankfurt. The train has been cancelled and now it says I can use any train. Does that mean that I can use any direct train between Stuttgart and Frankfurt or can I also use trains with changes (so let's say I take an ICE to Mannheim and then take a regio train or another ICE from Mannheim to Frankfurt)? Thank you!
