How to update the parent issue based on the child issues status change?

[Mykhailo Shukakidze]

Use case:
I have the issue that might have one or more sub-tasks under it. I would like to update the status of this issue only once ALL of the sub-tasks are closed.

Please help me with such automation conditions.

Thanks in advance

There is a template rule for exactly that in the Automation Rules Library.
