If a mistake is made when adding a passage to either My Passages or My Collections it cannot be changed with how the app is currently set up. Instead the app currently suggests that you choose what it is you want and add it again to that category. Over time that category could become very unorganized with several maybe a lot of duplicate verses.
I cannot delete a passage from my collection. It was a mistake I needed verse 23 and not 22 and I cannot remove 22. It gives the option to add a passage but it doesn't give the option to delete one
