Isolated projects are not showing in the Team calendar - permissions checked - similar projects display without issue.
Error message :
Unable to load events of M20 SMT Schedule (769f69e9-1268-4ef9-a9b1-b2b6fc9ee4f6): com.atlassian.confluence.extra.calendar3.exception.CalendarException: calendar3.error.jiralink
I'm having the same issue, appeared to happen yesterday.
The https://jira.atlassian.com/browse/CONFCLOUD-69580 issue that was created in March is not the same issue. This issue relates to linking JIRA issue via "JIRA Agile Sprint". In my case we have linked issues via "JIRA Issue Dates"
This has a big impact as we are using this feature to show calendar view of all our issues relating to releases.
I spoke to Atlassian support and this appears to be an issue dating back to March. However, it looks like our instance and yours both started experiencing this today.
Here is the original bug they mentioned. Be sure to vote for it either way.
Attempted a few work-a-rounds today :-
Has anyone got any other ideas?
