I already updated and I got the new version
I remember with the old version of Jira, I have 2 types of editor when I want to create the comment
But with the new version, I imagine that I have only 1 editor. To be honest, I do not like this one, because I can not adjust the dimension of the table.

Luckily, I found one thing. I can have another editor if I open the task from the Notification bar:


Please look at the URL of 2 pictures I uploaded, you can see those are different format
But I'd love the second editor than the fisrt one. My question is: How can I open this editor when I open the task directly, not from the Notification bar?
Thanks for reading and helping!
