@elilla "I'm guessing this must be a limitation of closed data access on the transportation companies?"

Yep, this is very likely the cause. All transport operators in the EU are *supposed* to be providing open transit data, but in practice that uhhhh doesn't really happen, or lots of barriers are put up to accessing it, so open-source things almost always have coverage gaps because they can't sign the NDAs that some operators require for access...

"address search wasn't as good as the DB app"

Out of curiosity, what makes it worse? I've never used the DB app so I'm not sure what the reference frame for a 'good' address search is here :P
