Dashboard pro version nag screen not dismissible

Hello @addonpro,

at least in 7.5.5 and also now in 7.5.6 the dashboard nag screen with the text “Contact Form 7 Cost Calculator: Enter Purchase Code below the plugin or Upgrade to pro version: https://add-ons.org/plugin/contact-form-7-cost-calculator/ ” is not dismissible. We can click on the “X” on the right over and over again, and it just keeps reappearing taking unnecessarily room on our admin dashboard. We think you will want to fix this glitch.

Greetings and thanks for your good work,
