Selma, all sharing is helpful and hard to come by, so much appreciated. What happened here is that my Twitter followers are a wide variety of people who aren’t on Medium and they said “oh heck no” I don’t want to see links I can’t see by low performance and unfollowing. It may not be the same for you. If your followers are hanging around, or are mainly writers it may not pose a problem. On my personal profile, peeps didn’t like it so much, so I mainly share friends link and unlocked pieces there. I share locked links in other places where writers are appreciative of seeing them. It’s just knowing where to share certain info with people who appreciate it. The lock function is at the very top of a piece and you can toggle it on or off after entering the title. It is a writer option before submitting to a pub. Hope it works well for you.
