Updated date doesn't include comments?

[Kimi Nakashima]

We just updated JSM (data center) last weekend to 4.18.1 and started noticing that the updated date on the issues wasn't updating correctly. When I looked further into it I noticed that comments were not being included as updates anymore. To confirm this was something recent I looked at issues that were last updated before we upgraded and sure enough if a comment was the last thing that happened on the issue the updated date reflected the date of the comment. It no longer does that. I checked the release notes and I didn't see anything that suggested this was a change made on purpose.

Is this just happening on our instance? Are comments not supposed to be counted as updates to issues?

On my cloud instance, I had to create to different Jira automation to solve my requirement ( a mail notification to assignee on a mail different than the primary one) and I discovered that update events does not contain the comment event.

 An update is for example a change in description, or summary, or change of status, or change of labels.

We have same issue. A possible workaround if the Jira installation is under your ownership: 

https://community.atlassian.com/t5/Jira-questions/JQL-for-Commented-by-user-and-commented-date/qaq-p/1410972 and check manually for updates in the comments.

However ours is a third party and these functions are not implemented :(
