Sadly, we aren't perfect, but we are trying to get there! Some minor bugs might appear. We are working on resolving the issues we know about.
Usability issues
Confluence-wide file upload may be broken when Linchpin Events is installed.
There currently is an issue that prevents users from uploading some files to Confluence pages when Linchpin Events installed in that instance.
This issue has been fixed in version 3.0.2 of Linchpin Events.
Plugin compatibility
Linchpin Events overrides Space Privacy settings.
When an event is visible to all users (and not restricted to specific spaces), all users will be able to see the event, even if Space Privacy settings would forbid it.
