Horrible plugin

Unfortunately, my client insists on using this as their payment gateway.

The SUMUP platform is so non user friendly and impossible to find anything you are looking for.
The setup of their test account is a painful process. And their online support is setup to be VERY inconvenient to ultise, but I guess this is their plan/intent. You have to VERIFY yourself each time you want to open a support chat. This is so, so stupid, as you are already logged into your SUMUP account.
Even when you do succeed on reaching support, the level is so low at the end they ‘pass the issue’ on to senior engineers, and this 99% of time never leads to a successful resolution.
I have used ALL the payment gateways, STRIPE, PAYPAL, even woo’s own one. And none were as difficult of as problematic to use as SUMUP plugin.

Even when working, if delivers on the checkout page of your Website TWO pay buttons. And still they have not fixed this one……
