Hi all,
Samsung did answer to my request, with the following:
Regarding your inquiry, we would like to inform you that the Gear Platform Version of your application (000001593509 / Classic One Watch Face) is 2.3.1.2, which means that the application should not be displayed on Gear device whose platform version is below 2.3.1.2.
Given the above reason, we would like to recommend you to make sure the used devices are updated to the latest version of Gear OS, then re-try to search for your application again.
Can you all verify that you are running at least this version on your device? And if not, try to update to the latest version of Gear OS?
In all cases, if you do not have the latest version, it is something good to get
Thank you all for your time!
Please keep me informed.
