@necrevistonnezr Thank's a lot, but app seems not manage two account on the same domain.
In my case, I use the rss.mydomain.tld with two users:
Personal use (with personal feeds)
Working use (with working feeds)
When I try to configure two different accounts on Reeder, pointing on the same rss.mydomain.tld, app tell: "Impossibile to add account because you have similar one".
So for now I'm using Tiny Tiny Rss + Fiery Feeds app, even if Fiery Feeds is full of bug and unstable.
