Manually starting a nap without setting a timer doesn't work.

My Fenix 7X 20.22 doesn't realize naps on its own. As a workaround I start a nap manually and with a timer it always works by waking me up. The nap is shown in GC. When I don't wanna use a timer it doesn't. The watch says "have a nice nap" and the screen turns into sleep screen. When I wake up I try to end the nap but it doesn't give me the option. I press the back button and the watch is in normal mode but in GC there is no nap shown. Also the watch doesn't show a nap. What's wrong?
