WindFree gone from API overnight?

Hi!
First post, not sure if right category :frowning:

I am developing custom integration for Home assistant, allowing extra features to my Samsung Windfree AC. I noticed today that Windfree option, which was under custom capability ā€˜acOptionalModeā€™ is throwing 500 error. State of device still shows acOptionalMode and itā€™s value, however there is no option to trigget custom capability as all custom capabilities are now gone from list of available ones for this device. Itā€™s supposed to be now in ā€˜airConditionerFanModeā€™ as ā€˜windFreeā€™, it accepts this as input for API but device doesnā€™t switch. Any ideas? Is this some bug introduced in new verison? If so, how can I report it so it gets fixed?

Nevermind itā€™s back on again. WTF is happening SmartThings devs?!

What is the syntax you are using to activate the Windfree option?

Hey, I purchased windfree a few months ago, love the AC but I hate that the smart things app cannot allow you to set a schedule for the ā€œwindfreeā€ mode.
Beats the whole purpose of it.
Have you figured out how to activate it?
