Is paying with paypal option gone?

It appears to still be there when I look.
In the new manager at cloud.linode.com, it's under 'Account' on the left, Billing Info tab, then expand 'Make a Payment'. There's a Credit Card/Paypal radio button (it defaults to credit card, click 'Paypal' to switch it).

In the old manager at manager.linode.com it's still there on the Account main tab, Make A Payment subtab.

I don't have the paypal button. I have been paying with paypal for at least two years and now the paypal button is gone on my "account/make a payment" page. That is why I am confused.

In the end I went to the old manager.linode.com page and there I found the paypal option so I solved it temporarily. I still don't know why the paypal button on my cloud.linode.com page is gone.

That's a bit unusual. I'd recommend opening a ticket. From there, myself or another member of the support team can take a look and make sure that PayPal payments are working in the Cloud Manager.
