after a long time and painstaking work, we finally fixed and upgraded the house numbering process. We ran the process on all the historical house numbers that were submitted but never uploaded, and most of them (64%) were matched properly and should join the map within the next indexing / update (up to 24 hours).
Most of those that failed, failed because the house number wasn't associated with a street (or to a street with no name), or they weren't in a logical sequence. Please check the house numbers you've submitted in the past, and if you notice that some weren't updated even though they are properly matched to a street (can be checked in the details section) or they are in a logical order (trust your senses), please update this post.
just so we're all in sync: Blue house numbers mean that they were approved and should be available for search / routing. White ones mean that they are waiting to be fixed (on the daily procedure) - the next day (assuming the process went through) they should turn to blue, or turn to red - if they were not approved. Red ones are either rejected ones, or house numbers that were not approved yet. When you save house numbers (on the cartouche) they will turn white, and hopefully the next day - turn blue.
If they go back to red for no apparent reason - please post here with examples.
Chris - I'm checking your question and will let you all know as soon as I have some conclusions.
