Unable to activate Pro License!

Hi,

I’m unable to add my purchased PRO License within the Settings Page of the Pinpoint Plugin as described in Activate your License here here.

At Settings/Licenses no field or button exists to add a License but only the following Text is shown:

Activate the plugin and add-ons to check and receive automatic updates. Activation is not required to use the items.

Let me know if you need further information and/or a screenshot.

I’m using WP 5.5.1 hosted at WordPress.com.

Thanks!

Best Regards,
Matthias
