I have.
Just started to get traction in my shop when suddenly nothing. I seem to be invisible and wondering if anyone else is experiencing the same.
Not me but you should enter your shop location so you come up in local searches.
@UrbanTreasuresShoppe: "Just started to get traction in my shop when suddenly nothing." Etsy seems to give new shops and listings a boost in search so that the algorithm can learn if people want what you are selling. This boost is temporary. Also Etsy is constantly tweaking and testing so there could be a million reasons for a sudden change in shop activity. As things stand now with Etsy search, you probably need to continually drive your own external traffic and sales.
