Hello,
Welcome to this forum.
Let me try to state your problems one by one (it’s better to discuss a single issue in a single thread, this will help others to track the issue).
Regarding the first problem:
- The complication has some properties. If you choose a complication and deploy it in your watch, the watch automatically selects the appropriate layout based on the complication provider.
- To implement one specific layout only, you must remove the unwanted layouts from the layout list. Or you need to change the color or other properties for all layouts.
This is some sort of complex, in this concern, here is a blog to manage this. Please check out this blog: Things to Consider when Designing Complication Layouts
Or you can check this forum thread: Complications have no colours
Please share if it resolves the first problem.
