Google announced that starting after August 16, 2016, all new AdWords accounts will include cross-device conversions in the Conversions column by default.
Previously, this was a setting your can turn on or off but now, by default, the column will show up for all.
Google said:
Your cross-device conversions will soon be included in the Conversions column automatically to give you the most complete view of performance possible and help you measure the full value of mobile. This will begin rolling out to advertisers starting September 6, 2016. The setting to manually include cross-device conversions in the Conversions column will no longer be available.
Google really wants you to see how the ads convert - so here is there go at it.
