Hello, did you find a better solution for this? Currently without much official information, I ended up finding a "solution" I get the available size informed via Geometry <- which can be inconsistent or via context.displaySize which is consistent... and multiply by 2. So I was able to make it work on Apple Watch of different sizes and with a good quality. Because for example on Apple Watch Ultra it is a limit and on Apple Watch Series 6 it is another size... Really the part of WidgetKit besides being poorly documented seems to be a "gambiarra" does not seem like something that was so well planned, it lacks several functions that already had in ClockKit. Hugs.

I also have the same question, do you have any evolution about this?
