Inter app audio, Audiobus, audio unit?

Really not thrilled with this update, tried using it with Audiobus, both 2 and 3 and it wont open , either as an output or input, and apparently as far as inter app audio goes you can only use other apps like Auria to use fl studio as an input, but you cant use other apps inside of fl studio. I have a ton of other synths and keyboards Id love to use inside of fl studio, I dont know why we cant do that yet, maybe they think people wont buy their iaps but that doesnt make sense because I already brought almost all, but even if I cant use outside synths Id like to use fx or run a guitar thru AmpliTube or bias fx and record into fl studio.
Id expect a new developer who hasnt done their homework to not have Audiobus or inter app audio but not a company that has been involved in audio software as long as image line has.
