When I authenticate my monthly usage plan, I get the message "This license has reached the maximum number of deactivations, so it cannot be activated on this device."
There is a limit to the number of times you can change the device on a monthly plan.
With a single-device plan, you can switch between licenses when you buy a new device, but you can't repeatedly switch between multiple devices while using the plan.
If you want to use Clip Studio Paint with multiple devices, please use a a dual-device plan or a premium plan, according to the number of devices you wish to use.
