Newsletters feeds don't update when consumed via API

Hi! Long time customer, first time (?) bug reporter. :wave:t5:

Newsletters feeds don’t update when consumed via API.

I use Newsblur almost exclusively via NetNewsWire. When used from there, I almost never see updates from my Newsletters subfolder. However, after I login via the web app (, then suddenly the feeds will populate with emails received since I last logged in.

Is this intended behaviour?
