Hi. We are using Magento 2.1.7. We are using Worldpay Online, but apparently their module only supports upto Magento 2.1.2. If you are using v 2.1.7, can you please recommend a gateway provider who will suppost this version. Also if you are currently using Magento 2.1.7 on Worldpay Online, which what plugin are you using? Can you send me its URL?
We are having success with the official extension on 2.1.7 (https://packagist.org/packages/worldpay/magento2-module-payments). What problems are you running into?
