Fatal error: Class Dfe\CheckoutCom\Method contains 1 abstract method and must therefore be declared abstract

Hello,
I have installed checkout.com using command composer require magento2/checkout.com:*
After this i have run command: php bin/magento setup:upgrade and I get:

Fatal error: Class Dfe\CheckoutCom\Method contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Df\Payment\Method::amountLimits) in /vendor/magento2/checkout.com/Method.php on line 21

Can you please help me to resolve this issue.
sincerely

checkout/checkout-magento2-plugin repository is broken because Checkout.com company misconfigured the Packagist integration.
Install the extension from the right repository: https://github.com/mage2pro/checkout.com
