Back to Feedly (for now)
I have given up on Reeder 5’s native RSS feed handling with sync via iCloud. I had expected my devices to keep in sync, and for Reeder to sync in the background rather than whenever I started it. I think I asked too much from it. I use three iOS devices each day, and Reeder was showing me stale content on all of them at various points each day. I suppose local device syncing of 75 feeds was a bit too much for it to handle quickly and smoothly. I moved my RSS subscriptions back to Feedly and am once again satisfied with multi-device support. I think I have learned that a web service works better for me, which probably should come as no surprise.
