Is there a dark mode available for Jira on the web?

[Matt Richards]

This is one of the last primary tools we use to not be running in a dark mode, and it's rough on the eyes every time we have to switch to Jira.

Sprints do not belong to projects, they belong to boards.

When you are clicking "create", it is looking at the boards that include this project and trying to add a sprint for the board it finds for that project.  You'll need to take a close look at what boards include the project.

I knew that sprints arent assigned to projects, but was under impression they are globally defined not assigned to boards, thanks for clearing that up.

I checked in Settings for ZXCV board and in General tab I only have assigned ZXCV project (Projects in board) and board is only shared with ZXCV project.
FYI Filter Query is: project = ZXCV ORDER BY Rank ASC

But I also have 3rd board on which I aggregated multiple projects including ZXVC but not ASDF and when I created sprint there. Sprint had name ZXCV #number

#Edit

So now after I created sprint on this 3rd shared board it appears ZXCV board is fixed. When I create spring I get ZXCV #number, but now I don't understant why I see first spring which was created in ZXCV board on this 3rd board but I cannot see any new sprints I create for ZXCV

#Edit2
Okay so apparantly you need to have issues assigned to sprint or wait some time till it's shown on other boards
