I just found out, that copy and paste doesn't work in 1.2 (macOS Sierra). Text copied from another program (word, pages) doesn't appear in manuscripts (I have the possibility to choose "paste" from the "Edit" - Menu). The same situation appears when copying a text from manuscript and trying to paste in an other word processor (word, pages) - it seems, like manuscripts doesn't copy the selected text into the clipboard, only an older entry (not copied from manuscripts!) appears when trying to paste ...
Copy and Paste not working in 1.2
@Matthias-Beck this is an issue with the 1.2 beta caused by a release build configuration issue. It's a bit complex issue to explain, but boils down to a component that's required to be built inside the app bundle being missing in the release build and it being found through another route if executed on the same machine also used for development (making it hard to detect it). Apologies, as I noted on the other 1.2 beta related thread, we've now added means of automatically detecting this anomaly.
