Every user has to set their own preferences for those options. There isn't a way to push the changes to all users.

The second screenshot is much closer to what you actually want. In your hierarchy building, you don't need to put all the individual marketing channels in there. Just make one classification, call it something like "Marketing Channel Groups" (or whatever terminology you use). And then when you downl...

The above two comments are great for explaining the options for the 'then' conditions, so I won't repeat that. But I do want to add there is one other thing to consider. In the top right of the segment you have "include everyone", there are also options for "include only after sequence" and "include...

When you have a sequential segment it's going to be made at a visit or visitor level. This level is important as it is not just the level where it looks for your conditions, but it is also the amount of information that will be returned. If your segment is a visit level, then it's going to look at e...

The step that you have done is just the first step to creating a classification. You've created the hierarchy, but now you need to assign the values. You can either use the rule builder or the importer. In your case, I think the classification importer would work better. You only need that first lev...

I'm not 100% certain if this would work for what you need, but in the date settings there is an option to "make date ranges relative to panel". You could try selecting that and see if it makes a difference.

I called this out to the team a few months ago when I did the practice exam, but if it's still there then it might be worth reporting it again. 

The way I would do this is I would first create a calculated metric for average monthly visits by doing visits (or sessions because I'm using CJA) divided by a distinct count of months.   Then you can put this in your table and add a time period column for YoY. Then from the table you just do a bar...

I agree with @Isha__Gupta that an evar is the best method to use. You can capture the actual values, yes/no. But unless you have another reason for capturing it in a metric too, you should just be able to use the 'evar instances' metric associated with the evar to get the count. As long as it isn't ...

There isn't a way to add "show all" for non admins as far as I am aware. What you can do instead is save projects in the "Company Folder." Any projects in that folder are automatically shared with all users in your organization.
