Can you use more than one dongle for different comps

I won’t be able to use my main studio as much anymore so I’m going mobile. What I wat to know is to make it easier is it possible to have two dongles. One for each computer but with the same lisence?? Or do I have to keep pulling the dongle out and putting it back again??

The short answer is no.
The license can only exist in one place at a time.

That’s poo. What about for an older version of cubase. If I had 7.5 on my main and 5 on the other? Possible?

If you are talking about two separate licenses, then yes. Otherwise no. Think of the license like a car. You buy one car and you get one car. You can’t get an extra car without paying for it.
