The Samsung Gear Manager app has today been updated to version 2.2.15022599 , but unfortunately there is no changelog available at the moment and no new features, at least what I can see, so we can presume this is a general bug fix release.
If you have not got a notification to update your Gear Manager App then you can manually update it via Samsung Galaxy Apps.
If you have updated to this version and are still having issues, you can install an old gear manager version manually until the next Gear Manager update.
Have you still got problems? Let us know in the comments below.
