I've just updated to the latest beta (4.25.1016) I'm not sure if this now includes the big, under the bonnet/hood, alpha updates that the team have been working on?
Either way, I'm still getting the Guide freeze bug that I reported and sent diagnostics here:
Another one that I previously reported is also still there but seems to have changed slightly - the API command to navigate to Videos (/api/navigate/Videos) doesn't work correctly.
On earlier beta versions if you are watching live TV it acted as a backup button (so if you were in Guide prior to Live TV it goes to Guide rather than Videos) but if you run the command again it did go to Videos. In the latest beta it still acts as a backup button in Live TV but once back in guide subsequent commands do nothing but seem to then cause the Guide lockup bug described above. ie no navigation buttons work and it eventually crashes to OS.
