Nextcloud version: 18.0.1-RC2
Operating system and version: Docker image nextcloud:18-rc-apache on Debian 9
Apache or nginx version (eg, Apache 2.4.25):
PHP version: 7.3.14

The issue you are facing:
I get the notification “Help improve Nextcloud” since NC 18.0. But when I try to answer by clicking on either one of the two buttons, I get the error message “Failed to perform action”.

Is this the first time you’ve seen this error? (Y/N): Since NC 18.0-RC, I see this message again and again.

Steps to replicate it:

  1. Click on the button “Notifications”
  2. Click on one of the two buttons of the message “Help improve Nextcloud”.
