Do/could/should we have a compatibility/known issues list for studio?

Are you sure u are “selecting” correctly? Clicking on a layout is not selecting its only for preview. You need to “x” it to really force to the layout u want.

You could also try hiding elements u dont need

Btw it could also be the pixel complication doesnt support that specific layout. When u first choose a complication type it allows multiple layout for different complication, and its up to the complication to decide which in the list it supports. (Make sense?)

Anyway see this guide…

What do you mean wrong complication heading?
