vCard file cannot be saved in mobile Phone contacts unlike Plugin Demo

Hi,

From your plugin live preview page (https://abcfolio.com/wordpress-plugin-staff-list-vcard/live-previews/), when I click on “Download vCard” on my mobile Phone web browser, it creates a contact where I could save in my mobile phone contact list.

However, when I install the plugin on my site and follow the step-by-step guide in your plugin documentation, I noted that after I click on download vcard, it does not create a contact for me to save in my Phone contact list.

After some checking, I noted that the “vcard” file that is downloaded does not have a .vcf extension. Whereas, the file downloaded from your demo page is a .vcf file. Refer to the following screenshot: https://estherg34.sg-host.com/wp-content/uploads/2022/08/Staff-List-vCard-vcf-file.jpg.

Could you advise if there is any configuration that I have missed out? Or that feature is only available with your Pro version?

Regards.

Esther
