FWIW, the 'old' version never let me down when using it on channels and busses (not auxes...)
@ audiomichael: While in most software a bus is just a mix 'somewhere', which you can return on an AUX channel, in Logic you can have BUS objects in the environment.
These BUS objects also feature insert ports, tho no sends. The picture you showed is of an AUX object, not a BUS object. BUS objects are standard NOT there in the environment, but you add them yourself (see pic below).
As output of the new BUS object, you can select the AUX channel of your choice. On an insert of the BUS object, I place the I/O plugin and Latency Fixer. This way, I have no latency issues at all for hardware inserts on a bus.
