I know there's no plans for manual channel selection but network optimization keeps picking channel 13 on my X60, and due to this, some of my smart home devices, such as my Ring Doorbell, is unable to connect as it can only see channels 1 to 11.

At least give us an option to limit network optimization to channels 1 to 11, while 12 and 13 is allowed in the EU, not all devices can actually use them.
