Apple also recommends using 20MHz for the 2.4GHz band.

 

• Set to 20MHz for the 2.4GHz band
• Set to Auto or all widths for 5GHz and 6GHz bands

 

Channel width specifies how large of a “pipe” is available to transfer data. Wider channels are faster but more susceptible to interference and more likely to interfere with other devices.

 

• 20MHz for the 2.4GHz band helps to avoid performance and reliability issues, especially near other Wi-Fi networks and 2.4GHz devices, including Bluetooth devices.
• Auto or all channel widths for 5GHz and 6GHz bands ensures the best performance and compatibility with all devices. Wireless interference is less of a concern in these bands.

I hope TP-Link gives us the option to choose within the next firmware updates...

Yep, saw that Apple document posted on other threads here too. It's weird but I did start having bluetooth audio problems after the mesh was put into service and one phone is always needing to have its wifi turned on and off to get any internet on the mesh. They have been promising this for years by the looks of the other threads but TP link keeps replying with ideological reasons why they won't allow people to have more control in the options.
