Acoustic sealant - green glue at seams & joints

Maybe have a look at the installation details, good video too.

Has anyone just left the sealant exposed at the ceiling and not done the muddling over top?
Thanks

Sealant is not needed at the joints. Tape and compound is sufficient.
Just using acoustic sealant does not do much good if you don't do the other things to make an acoustic sealed wall or ceiling. Sealing a room acoustically is much more then the glue. Otherwise it is just gluing the drywall to the the studs and anything will do.
