Issue Summary
Event reminder notifications in WATCHED CALENDARS do not consistently fire. When adding a single user to the 'WHO' section when adding a new EVENT, these reminders fire off intermittently. When adding multiple users in the 'WHO' section, these EVENT reminders never fire off.
NOTE: WATCHING the CALENDAR means that the user has ADDED the CALENDAR to their CALENDAR (user logs in, selects CALENDARS at the top, adds the newly created CALENDAR and turns on reminders for that calendar).
Users that are simply watching the SPACE or PAGE that has an embedded CALENDAR only will NOT receive EVENT reminders when added to an EVENT on this CALENDAR.
Steps to Reproduce
Tested using Confluence 7.10.0 with TC 7.0.17. Some admins may also see the issue in Confluence 7.11.1 with TC 7.0.17.
- Install Confluence (latest) with TC (latest).
- User A creates a CALENDAR for a space. Setup the EVENT type reminder for 10 minutes (same with Custom EVENT types).
- User B logs in, navigates to CALENDARS, adds the new CALENDAR to their CALENDAR.
- User C does the same as User B.
- User A adds User B and C to the 'Who' section of the EVENT, both of which should be WATCHING the CALENDAR.
- Set an EVENT for 15 minutes in the future, end an hour later. Set a description.
- After saving the EVENT, you should see an reminder email fire after 5 minutes (not an add user or add event email).
Expected Results
The EVENT reminder is sent out to all who users who are WATCHING the CALENDAR and were added to the EVENT 10 minutes before the EVENT starts.
Actual Results
The EVENT reminders is not sent to anyone. For a single user, the EVENT reminder is sometimes sent, but is intermittent.
