So the latest official stable update that came yesterday or the day before broke the RGB lighting with iCUE Link Hub.
Instead of spreading out the RGB effect across all devices connected to the Hub, it instead now only lights up the Pump block on the 360 Titan AIO cooler.
What app version are you on? Could you please try the latest beta to see if that fixes the issue?
To access the latest beta version, go to Settings > Updates. Enable the slider next to “Enroll in Preview Updates”. This will download the latest beta version. Once done, pleaes restart the app and check if the issue has been resolved.
Sorry. I opened a duplicate of the topic by mistake. Just close this one. The preview update fixed the issue. I have the RGB effect running smoothly as it should.
