Where is the Data Import Wizard after Update 1 in CRM 2015?

Hello,

I cannot find the way to map fields while importing my template with new records into CRM after we got the Update 1 in CRM 2015 -online- last week. Once I select the file in the Import window, it goes directly to the final screen when it asks if we allow duplicates but it never gives me the option to chose my data map. I try importing my spreadsheet but it will not work because I'm not using the primary field as reference but an unique identifier.

Any help would be very appreciated :)
