Terribly slow even on my Galaxy S20+, I'll stick to creating my faces on my computer, this is a good idea, I managed to create 1 watch face but my second one that I selected a picture from my phone then it was just way too slow, think its too buggy, just kept freezing so I decided to create the unfinished one but it just kept saying to choose the category and it wouldn't get past that part so couldn't even save it, Way too time consuming, must of spent over an hour on it. No Thanks.
