Cannot buy watchfaces

Whilst i can easily download free watchfaces from my iPhone 8 to my Samsung Gear 3 Classic, but when i attempt to buy a watchface Facer on my watch states „no device found“. Whats that?

Hi! Sorry about that, can you share a screenshot of that error?

I have tried again to send you the snapshot with the error but this time Facer responded “get Facer Premium”. How can i get Facer Premium?

Any chance for an answer by Facer?
