Jutland's missed opportunity and the Baltic

What were the major missed opportunities at Jutland?

Britain might have turned a clearer victory into Baltic pressure if reporting and destruction of German ships improved; Germany's better chance was to isolate the battlecruisers.

Better reports from Beatty could have helped Jellicoe inflict heavier losses on the High Seas Fleet. In this counterfactual, a decisive German defeat would allow the Royal Navy to push through the Danish straits into the Baltic and blockade Germany's Baltic coast. The predicted result is a much earlier end to the war, although that depends on the fleet victory opening the Baltic route. Germany's opportunity was to draw the British battlecruisers farther south and time its attack more carefully. The Queen Elizabeths are judged capable of fighting their way out even if the battlecruiser force were caught.
