Timeline dates disappears after refreshing the page without a clear reasoning

[roberto scilipoti]

Dear Team,
My team and I would like to maintain our roadmap using standard timeline Jira functionality:

However, after we update the start and end dates for our items, the timeline bars disappear when the board is refreshed.
We are unsure why this is happening.
Could you please support us and explain how we can properly use the timeline functionality?
Any guidance would be greatly appreciated.

Here you can see what happen after we refresh the board:


Best Regards
Roberto

We identified the root cause of the issue. There is a Jira automation that automatically copies the due date and start date from child items to the parent item.
Since our board displays only epics, this was causing the issue.
I’ve now started maintaining the timeline in a separate board, and with this adjustment everything is working as expected.

Hi Roberto,

I am wondering if this is a browser problem. Have you tried a different browser, cleared cache, or tried with Incognito or Private window mode?

Hello @roberto scilipoti 

I have not seen this occur in my own Jira instance, but another person reported the same problem earlier this week:

https://community.atlassian.com/forums/Jira-questions/Gantt-Deadlines-Disappeared/qaq-p/3207362

Have you confirmed that the date information is still actually present in the issues for which the bars disappeared? And set to dates within the range of your display?

Have you tried a different browser app, or private browser window?

Are multiple users seeing this effect?

Since you are on a paid subscription you could report this to your Jira Administrators and they would be able to open a support case directly with Atlassian Support.
