Connecting to network performance issue
Shortly after the Shelley upgrade, Daedalus took longer to verify the blockchain and connect to the Cardano network on startup. This issue is being addressed by optimization work for Cardano Node performance, and will be resolved in upcoming updates.

Stake pool ranking is currently randomized to avoid unfairly favoring certain pools over others, while historic data is not available. This issue will be resolved in an upcoming Daedalus release once historical data becomes available.
