Hello everybody!
We've just switched to Jira Cloud and our users are asking for functionalities that were working really well for them on the on-prem instance. One of these is the "Actions" (three dots icon) for the sub-tasks when they are viewing an issue.
This is what it used to be - notice the 3dots icon on the right side when you hover over the sub-task:

And this is how it looks now:

The Actions button was helpful as it helped transition, log time, etc. on the sub-task without having to open the sub-task
Please let me know if you have any ideas where to find and edit this option.
Many thanks in advance!
Gabriel
