WP reader don't show up my posts

Last week I moved my blog (tifabene.wordpress.com) from to wordpress.com to self hosted service (oplatifabene.it).
I followed these steps:
a) export/import all contents and media;
b) make the wordpress blog private ( tifabene.wordpress.com);
c) install jetpack and connect it with my wordpress account;
d) buy a redirection service from wordpress.com (tifabene.wordpress.com ) to my new blog web site ( oplatifabene.com);
e) migrate my followers.
So everything goes right: follower, stats but my new posts does not appear
in a WP Reader. I tried by searching with tag and category but all posts ( newest and olres ) are completely disappered. How can I fix it? Thanks in advice
