Here is a new process that has been successful for my site

1- Connect to your Sumup dashboard
2- Click on F5 and Shift F5 in the Sumup dashboard to delete history of the page in the browser.
3- Run the process of installation of the plugin in WordPress dashboard.
4- When you have the information “See the plugin”, click on F5 and Shift F5 to delete previous history
5- The plugin is installed and I verified that it was effective.

Hope this could help
