Once you register a new account you will be asked to verify your email, so you can use all of the pCloud features and options. To do that, just open your email inbox and check for a verification email from pCloud. If you don't see one, check your Spam folder. If it's not there either, click the Verify Now button on the top right corner at my.pCloud.com and request resending a verification email. Note that you can also request resending a verification email through any pCloud app you use.
