I installed Nicestats on two computers but it's only appearing on one

You can install Nicestats on as many devices as you use to earn extra Shells per survey.
Please keep in mind that all the computers where you have Nicestats installed will only count as one device when receiving the Shells (since it’s the same type of device). So if you have it installed on two different computers, you will still receive the extra Shells for one of those, as a single device.
To earn more extra Shells, you can also install Nicestats on all the mobile devices you use, smartphone or tablet.
