Why the date in Updated field is different from the last activity date?

[Aleh Charnetski]

Hello, community.
There is an issue in Jira that has an Updated field value of May 13, 2024 at 4:36 PM
whereas issue Activity doesn't show any changes on that datetime. The last activity logged is on February 12, 2024 at 4:23 PM.
Why the Updated field doesn't comply with the Activity logged?
How can we find out what was changed when the issue was last updated?

Hi @Aleh Charnetski -- Welcome to the Atlassian Community!

Disclaimer: I do not work for Atlassian or any marketplace vendor.  With that out of the way...

Please review your marketplace addons / apps to learn if any are associated with this issue's project and have made issue updates.  For example...

Based on the image you posted, I observe you have a checklist addon, which has its own history of changes.  When changes are made, they may not appear in the issue' history / changelog, even though the Updated field changes.

I tested that with the addon Issue Checklist Free, adding a checklist to an issue, and I observed:

• the issue history did not change
• the checklist history did change
• the updated field did change

I then also looked in the source changelog entries with the REST API functions to confirm that this is not a display issue: there are no entries for that addon.  This means the addon did not log that change.  Other addons may use the same practice.

Kind regards,
Bill

I didn't think of addons for some reason.
