Those of you who care about this issue, please fill out THIS
survey and let Logitech know you want this feature back. This is the first time they've specifically asked customers if they want sequences.
Those of you who have the ONE still have sequences, but they've been removed from newer models. So when the ONE is no longer made, you'll lose them unless you speak up.
The survey also hints at taking away the HELP feature, so if you want to keep that, now's the time to speak up as well.
It sounds like they're trying to decide which new features to add to myharmony.com, possibly at the expense of others. So if there is a new feature you want or an old one you want to keep, please let them know.
