I have found that running 3.03, my RooDials are significantly slower to reconnect from sleep when touched – it takes a full second or more to be become fully operational. I have reflashed one of my Dials back to 2.3.3 beta 5 and wake up/reconnect is near instant again.
Just reporting – I’m fine running to 2.3.3 for now, but open to a bit of experimentation.
(Two Dials, Pi3B and 4B, no BT extenders).
