But this is not the Apple logo slot, it is the slot for my app's logo. How do I configure it to show my App Icon from Xcode UX?

Like I said in the original post, I have a timer that updates a display every thousandth of a second on the screen. The display has no problem in Watch Ultra AFAIK but breaks down in the watch unless I use Watch 5 series after restarting the watch, then everything works fine. Anything unclear or do I need to explain everything better?

Did anyone look at this question and have a response?
