Synching to iOS devices

I am trying to syn entertainment to my Apple Mac. I follow the steps however, there is no option to Synch as indicated in the instructions. I have an iMac Pro with 128 GB memory, Processor 2.3 GHz 18-Core Intel Xeon W
Graphics Radeon Pro Vega 64 16 ; Startup disk 4 TB Feb 2021, macOS Sonoma 14.6.1. Phililps Hue is also not working with my iPhone 14, iOS 17.6.1 (up to date as of this post on 9/4/2024). Can anyone point me to some trouble shooting suggestions ? I’ve already spent about 3 hours on this with no solution in sight. Thanks.
