I’ve found a mostly consistent way to reproduce this. When viewing a document that is more than one screen long, scroll to bottom and attempt to paste.
- Scroll to bottom
- Move cursor to last empty line in document
- Tap to right of the cursor
The desired behavior is that tapping the cursor should bring up the iOS context popover that displays the paste command. The actual behavior is that nothing happens.
I understand that there are other options for pasting on iOS but none of them can easily be done one handed. The preferred interaction would allow pasting text using just a thumb on the screen.
