Greencard Interview Recommended Approval

Hey guys my and I we had our marriage interview January 28th 2019 in Cincinnati. It went well and the Officer recommended approval. Since 2 year anniversary is Feb 19th the officer told us he will attend a conference in Denver and will be back on the 20th Feb and he will submit our papers when he’s back so that I get 10 yrs instead of 2 year conditional Green ... Since then haven’t heard anything, my attorney made 2 inquiries and they never responded, the only thing when I check online it says Name ,date or birth update . Is this normal Guys ? How long did it take you to receive your card after you got approved?
