I am curious how do I increase the row count of a custom description field for the Cloud product? Currently defaults to 20 rows, I would like to increase the default to 50 rows.
Your link didn't work for me, but I believe this is the same article. I noticed that the article addresses customization available in Jira Server (not Jira Cloud).
I'm pretty sure that this level of customization is not available in Jira Cloud.
I think I've seen some (possibly outdated) suggestions that certain browser extensions might be able to tweak the specific CSS for that field (since it is a presentation/view issue, not a data/model concern). Seems like a brittle approach, not likely to scale across different browser types. But that approach might have merit if you "just gotta do it".
