Interesting. My app allows me to have them separate, so I see all the up separate from all the down, and always have. I refused early on to use anything that combines them because I want the full picture of engagement.
If you use an app, check through the settings and see if it’s supported (all the iOS apps I tested have it). Idk about web, might be something to look into tho since the data is all there, so it’s just be a matter of handling.
