Combining rank and priority is indeed confusing, since the priority field can contradict the rank. In most agile scenarios it is outright pointless. Multiple tickets can have the same priority but only one rank, so rank is more precise and useful anyway.

I found that I can enter a data URL as the image on the Priority definition, which helped a ton since I don't have filesystem access on our Jira server.

Would be good to do this in Cloud too.

If this is fixed in server, will it be fixed for cloud as well. Do I need to raise this as a separate ticket?

I hope Atlassian could quickly prioritized this function...

Another workaround: https://confluence.atlassian.com/jirakb/how-to-hide-priority-icon-in-agile-board-779160907.html.

I found that on community: https://community.atlassian.com/t5/Jira-questions/Jira-Hide-Priority-field-from-list-views-and-cards/qaq-p/622226

It would be great to generally manage "default" fields like priority or epics rather than only being able to manage "extra" fields on cards, both in backlog as well as active sprint/kanban board.

Daniel,

Attempted to put your CSS above in our Announcement Banner but it just shows it as text in the banner

<style type="text/css">
.ghx-priority

</style>

My need is to replace the standard Priority field with a Custom Severity field; so requiring general configuration of the Plan View columns.

A "workaround" would be to forcefully hide the priority icons with CSS.
Put the following in your announcement banner:

<style type="text/css">
.ghx-priority { display: none; }
</style>

Save it, and reopen your Agile board. Notice the icons disappear from the plan view and work mode. This is a hackish way of doing things, so it may or may not break other UI elements. (a quick test shows that it works fine) Test it thoroughly before deploying it into production.

I would expect that the priority icon disappears at least when I hide the Priority in the Field Configuration. But this does not work either.

I too would like to see this incorporated at some point. It can be visually confusing looking at priority icons when tickets are stacked in rank order.

Many thanks for reporting this issue. We see it as a valid feature request however we cannot provide any guidance at this time as to when, or if, we'll be implementing it.
