I'm wondering if the guided upright tool works at all on iPhone (16Pro with the latest iOS). I guess I've tried all kind of approaches for it - and only once I was able to get the guides visible. With the auto option, the result is pretty OK but when I choose the guided variant I do not get those guides - except that one-time success! So, please let me know if the function is just that buggy, or is there something I don't figure out??? Thanks!
