I purchased this plugin a few weeks ago and it was working fine, but encountered this problem today. The live demo doesn’t work either, which means it is definitely a problem with the plugin: https://zeroqode.com/plugin/link-info-and-preview-1548323062698x581843419560935400.
On my app, the error message says my app was “unable to connect to link preview - link info.” Can this please be fixed ASAP? Thank you.
