Hi,
We have created a new instance of confluence cloud to make some tests and we see differences between this one and our main one.
The new one is better and seems to mix classic and next-gen features, i.e for changing statuses of an issue via a dropdown menu like you can see below:


Does anyone encounter this as well and how to make my projects in classic mode on my main jira be like the classic mode projects of my test jira (knowing that in both cases, it's the same version, without any modification)
Thanks 
Seb
