I get that and somehow I can understand.
My question is why Waze didn't started with numeral and non numeral from the scratch. In terms of developing something like this from scratch it is really no difference.
I see how starting with only numeral system and then after a while some guy from a remote country starts to cry about not having non numeral characters could be a pain in the a**.
But Waze should have thought this from the beginning and start develop with this in mind. As a developer myself I don't see how starting with both numeral and non numeral system would have been more difficult for a developer. It is really no difference.
Anyway it's a little bit late for that but it's really a shame that such an important feature is released and I can't take any advantage of it. And more than that, it will be a shame when I will see confusion between new editors asking why they can't enter a correct address number. And the final user will sense that too because when you're expecting an app to do something, you really expect to do it properly. In my town going to number 18a on a street and going to 18g it is really not the same thing.
I'm even starting to consider not to add any number on those streets with letters in their address because will lead only to many angry users. And it is really not why I take my time to edit Waze maps. And it was always my belief that instead of a really bad data it's better with no data. That way the user will inform himself from another source. Just my thoughts, I hope nobody will see me as a really annoying guy for what I've wrote
