You know one of the reason that might result to this on your account is CRYPTO such as bitcoin to be flagged on your account. Paypal have been strugling with the choice to go in on CRYPTO or not. Just the other day I called in and all they could say is they might change the policies on CRYPTO though in the future. Localbitcoins have enabled paypal as a channel of payment i don't understand why the reject and yet they know thousands of trades use their services/platform.
Now one has to wait for 180 days so that they could access their accounts and obviously their money. 6 months for just trading bitcoins on their platform. This is mad but as all say CRYTO is here to stay and in Kenya we accept the challenges that come with it such has scams and frauds.
