I can't select words from questions and comments, except answers. Holding down the word doesn't make any selection appear. Sometimes you wish to be able to copy the text in there, for example a user who doesn't use English characters in their name.
I use iPad 2, app version is 22.214.171.124.
Today I find this question can be selected, although a new update hasn't been released. The linked question above still can't be selected. Some weird here.
