Hmmm I’m not sure why you’re not able to see them, do either Block Screen complications or widgets show up for you on Watch. Here’s what I’ve got that I see 👇
nostr:npub1reezn2ctrrg736uqj7mva9lsuwv0kr5asj4vvkwxnrwlhvxf98tsq99ty4 how do I get previews from the App Store to work as a watch face on the Apple Watch? Block screen faces aren’t available in the options?

Apple Watch complications 
Apple Watch widgets 
I’m dense! Didn’t even realise I could do widgets on my watch. Thanks so much 😅 had a play around and got it to work. Anyway to add something different to the compilation?
Nah you’re not dense some of this is just new (widgets on watch) and obscure, you’re way ahead of the curve here, way to play around and get it to work! What are you looking for added to the complication?
Similar stuff to the widget. Unless it’s already there. Price mempool fees etc
Yeah they are available for complications too BUT most of them are only available as accessoryRectangular size because the other sizes (accessoryCircular, accessoryCorner, accessoryInline) have such limited space constraints I couldn’t make them fit+look how I wanted them to. Here’s Modular face with the mempool complication
