Hi.
I use NNW on four devices (2x MacOS 26, iPadOS 17, and iOS 26). Normally, on all devices the latest beta versions (via TestFlight) are installed.
Often I read/check all articles in “Unread” until it is empty on one device, mark some with a “Star” for Favorites. I also wait some seconds before quitting NNW, or click on “Update”, hoping the the status of Read articles is saved in the iCloud. Some time later I use NNW on another device, and - sometimes more, sometimes less - articles, which should have been marked as “read”, are again in the “Unread” folder. But also sometimes I see new (previously unread) articles only - which is the behavior I expect in case of using NNW some time later.
“Sync content unread articles” is deactivated on all devices.
Is there a “trick” to be safe for a full sync?
