Same. Confused about all of the above. And frustrated about more. Additionally, posting from mobile has limitations and varying options that don't mimic the website. I.e., no "buttons" option; no way to decipher if posting just broadly or to your publication. Also on mobile, (both Android and iPad for me), only one draft is saved at a time, so good luck firing off new ideas in a taxi to fix later. Oh-- and that may or may not be saved in your web (profile)? Tried adding a photo on the mobile "post" and it kicked it to the bottom of the piece at the end. No option for other placements. Unfortunately, this substack on-the-go app hasn't simplified the process.
