Marking this as hold, we may have to adjust and backport the changes done for 8.7 now with the release scope change.

Approved, just a rewording suggestion 👍 🚀

@panagiotisgts It makes sense that this doesn't need to go into the latest docs, and this issue only applies to 8.6 as it is fixed in 8.7, but just want to confirm this is correct?

Suggested change

	- Unable to perform operations(assign/unassign/complete) on Camunda User Tasks, formerly known as Zeebe User Tasks, in Tasklist
	- In Tasklist, you cannot perform operations (assign/unassign/complete) on Camunda User Tasks (formerly known as Zeebe User Tasks).

	## Known issues

My question regarding this section is around wording alignment regarding "known issues" (same as "limitations"). I wonder if a note in the components list would be more effective, particularly as we can use that to encourage any users to move to 8.7, if this issue isn't going to be fixed in 8.6. @theburi is there any product opinion here?

I think we can keep it as is. I don't think people will navigate to other pages.

	- In Tasklist, you cannot perform operations (assign/unassign/complete) on Zeebe User Tasks.

I believe they're still Zeebe user tasks in 8.6; I am not sure if we plan to backport that name change.
