Archive premium RSS folders

As a premium member I just found the RSS folders but they don’t really work well in the other reader app I’m using and I think it’s due to a limitation for premium. I can subscribe but I get a trickle of articles that doesn’t reflect the amount of articles in the feeds throughout the day. If I upgrade does the flood gate open up?

Thanks.

Yep, exactly. Archive premium gives you the full feed. I believe you shouldn’t see any articles as a premium account, but I may have let some through for a user who wanted time to switch.
