"Hanging" alerts on the scanner
I figured I might as well report this to the new bug tracker. This issue has been present since the start of Prime.
In the bottom right of the scanner, the last alert is shown to the player. There's no timeout to this display and it should have some x amount of time to no longer display an alert. (maybe 24 hours?) It seems cumbersome to display the last alert when there's also a tab to look at the history of your alerts. I'm surprised there's no placeholder for this section.
Attached screenshot for reference. The portion where "Portal Under Attack" is shown.
