What type of device are you using? Have you tried resetting your network?
You can locate that by going to Settings> Search "Reset network" and run the device in safe mode.
Give that a try and let us know if this resolves your concerns.
I did everything I could to get Bixby hidden or off my phone. It's better that way. I think it's still installed because you can't remove it, thanks Samsung, but I don't know how to access it anymore and I'm happier for it not getting in the way.
