I was trying to refer other issue on my project
But they didn't appear on the issue list or searchable by any means
See the attached image below
There should be issue 119, 121, 122 but they are missing (they exist)
Hi @Yonghee Kim
Adding to Deepanshu's answer, the linked issues section shows recently viewed issues in the its results, or issues from your last issue search (eg. your Current Search). So if you've not viewed or searches for those missing recently, this is why they're not in the list.
You can just enter the issue you want to link to and it'll work - or you can click hyperlink "search for an issue" to get a specific list to choose from if in classic view (which from the screenshot it looks like you're not, you're in the new issue view).
