I faced Mantaflow bugs (ubuntu20/blender 2.83.9):
Fluid/Flow/inflow/ intial velocity have to be very high (20 in my scene, 1 in the tutorial)
Fluid/Domain/Cache/Type modular break render randomly: use Final always
Fluid/Domain/Adaptive Domain can randomly break at domain border : no solution for now
Material loose major voxels packs at render: It seam related to use of ColorRamp for smoke density
