Package updated to new version, however apt finds only the old version

I had created and uploaded a basic package, and tested by installing it. However, I found some errors so I fixed them and updated the package to a new version (1.0 -> 1.0.1). I made the changelog in the required way and uploaded to Launchapd, where it built successfully (.deb, tar.gz and .dsc files). However, there is a note saying:
" Note: Some binary packages for this source are not yet published in the repository."
Moreover, even when I update apt and apt-get, I still get the old version of my package. Even on removing and adding my PPA back again, I still get the old version (1.0). How do I fix this?
