On a recent update the ability to copy only a portion of text instead of the entire text was removed.
This causes a problem when a 2 step verification code is sent to my device because the message will usually contain other words that are not part of the code, and all I really want to copy is the only part of the message that matters. It also makes forwarding messages cumbersome when I have to delete the part of a message that is not relevant to the next receipient. PLEASE bring this functionality back!!!
