New version of Musescore 3 and Key Signatures
According the handbook on entering key signatures, https://musescore.org/en/handbook/3/key-signatures#add-key-sig-to-staves, when you click on a single staff in a score and double click on a key signature, the signature will apply to all staves. Now it is only applying to one stave. The only way I have found to apply to all is to select all and then click on the key signature. Is this the new desired outcome?
