Capo transposition Dorico App

Can anyone help
Using the Dorico app, writing out some Albert Collins. I have changed the guitar tuning, but I can’t see how to add a capo. I can see the capo and transposition section! But it doesn’t do anything. Some info would be great, whilst I can show the open strings on the tab, the notation pitches won’t match the notes on the recording.

At the moment, it’s not possible to define a capo for a fretted instrument in Dorico for iPad, I’m afraid. We hope to implement this in future.
