It appears that the online help is now for 2.2. What happened to the 2.1.x help? I still have folks using 2.1.x 'till 2.2. is approved for the network (long time). With Arc Map help, there's a pick list thingy so you can pick the version, why does the Pro help not have that? Is the 2.1.x help archived somewhere? There are subtle, yet, confusing to 2.1.x users differences between 2.1.3 and 2.2 when, for example, a 2.1.3 user is looking at Take a map offline—ArcGIS Pro | ArcGIS Desktop and sees a description of how to take tiles offline, yet that option does not exist in the version they're using.
