Read posts disappear from "All Unread" after a refresh on Mac after adding feed through web interface

[SilverEzhik]

I have an issue where sometimes the behavior of the "All Unread" feed changes from what I expect is the intended behavior. Normally, after a refresh, the "All Unread" feed keeps all the visible posts and just adds the new ones on top. However, sometimes this behavior changes: articles that are not marked as unread will disappear from the feed whenever a refresh happens. This is triggered both by manual and automatic refreshes, meaning that read articles will sometimes vanish unexpectedly. This even affects the currently selected article unless it is marked as unread.

Unfortunately as this is an intermittent issue, I don't have the concrete steps to reproduce it, but I suspect that this issue might happen whenever I add a feed through the Feedly web UI, rather than NNW itself.

This issue can be temporarily fixed by removing my Feedly account from the settings and adding it again.

I am using NetNewsWire 6.1 (6106) on an M1 Mac running macOS 13.2.

Are you saying that read articles disappear or unread articles?

Read articles without the little blue dot.

Tried to get a recording of the issue in action.

@SilverEzhik Thanks for the detailed bug report. We have had this reported before and never been able recreate it. Now that we know it is from adding a feed, it makes so much more sense why this is happening.

My default view is All Unread. What I often do as a workaround to this problem is press Cmd-1 followed by Cmd-2: switching temporarily to the Today view to immediately go back to the All Unread view. This clears the read posts.

In case it makes a difference to reproduce this issue, My only account set up in NNW is for Newsblur.
