I covered this many times already and it's in my guide since 2016.

Basically close your laptop lid until the projector monitor becomes primary, then open the lid again. Then both will be on.

As quoted in the known issue section, this only occurs on a clean boot. If it's gone through a sleep cycle once, you won't have this issue.
