Editing Text
In iOS 12, If I misspelled a word and I wanted to edit it, I would press and hold on the word and move the blue line until it fell between two letters.
Now, in iOS 13, if I do this it selects and highlights the entire word.
There's no way to select which part of the word I want to amend.
(I could move the left and right blue lines but it is tedious and too long winded).
I have to delete the word and type it again.
This is true for all apps.
iPhone 11 Pro, iOS 13
