I have recently installed Notion for iOS on my iPad Pro and it works. I wanted to try Notion on my M1 iMac before I purchased it as there seems to have been some issues posted, so I downloaded and opened in Demo mode. It seems to work fine except that there is no sound. Is this a function of it being in Demo mode, or is something wrong with the software on an M1 Mac running Big Sur? I have checked preferences and the iMac speakers are selected. My iMac volume is fine, not muted. When I start a new score, and open either the piano keyboard or the guitar fretboard, the speaker icon will not highlight. I can enter notes on the staff, but when I click the play button, the cursor moves across the staff, but there is no sound. I am very new to Notion, so I may be doing something wrong, but I can't figure out if I am doing something wrong or there is some incompatibility with my hardware setup.
