Nope, tried to publish the watch face 4 times. Once last night and 3 times today in the morning. Certainly, everytime I had to create it again, because no, it didn't get saved in the creator page.
Fortunately I managed to transfer the watchface in my Galaxy Watch, so atleast I can see my creation
EDIT: Found the reason why my watchface gets lost
"This content was automatically removed due to suspected copyright/trademark infrinmentge."
I get this info only when I click "view" watchface right after I try to publish it. That's why I didn't get any notification, because after publishing I clicked "My profile"
