Hi Barry
1. Yes, Event Aggregator will no longer work after one year. Unlike our other plugins, this plugin relies upon our servers to process importing events. When the license expires, support and access to that process expires as well.
2. Can you share the link you are trying to import? The Other URL is limited at this time to only other sites running WordPress with The Events Calendar v4.5 or higher. However, I believe Outlook can provide a .ics link that should work.
3. We do offer Calendar View Shortcodes and Widget Shortcodes for embedding the calendar, however, these are limited to Events Calendar Pro users.
Is there anything else I can help you with?
Thanks
Courtney 🙂
