@leocg I have manually recreated the Speed Dial page, so whatever that's there is now irrelevant. I'll try with another Opera instance and let you know. Thanks for trying to help.

@leocg No, they don't. There's no such thing as Other Speed Dials.

If I have Opera One on one device, it should be synchronised across my other devices. I expect it to appear on the other device (Windows 11) exactly as it does on the first device (macOS), even if they are running different operating systems. However, that isn’t the case. Passwords synchronise, but the Speed Dial does not. Are there any reasons for this?
