Cloud version of JIRA has certain limitations when it comes to displaying proprietary data, such as Frontlog's priority score. As part of those limitations, it is not possible to display issue priority scores in the backlog - the priority score can only be seen per issue on the Issue screen.

You can, however, use card colours to indicate the priority score value.

Since it makes little sense to assign individual colours to every possible score value (1-100), we recommend using a 9-step scale, with examples provided in the table.

Note that the range of the lowest priority step is the biggest since the need to differentiate between the least important issues that usually are at the bottom of the backlog is minimal.

When configuring card colours, select they Query based option and add colour values as per example in the screenshot below.

Feel free to use a different number of steps or your own colour palette. Please refer to this useful resource for colour palette ideas.
