Hi Peter, i am not a big user of join a session as i am a solo performer mainly, but have used it on occasions when i have a guest, i have just fired it up and found things that dont work well, so i thought id mention them, i expected my text size to be automatically adjusted to suit my device, my host is a 10.5 inch ipad pro,my default text size on this device is 50pt , when i join to a slave like an iphone 11 pro max i expect this 50pt setting to be automatically adjusted to suit the Iphone screen so it looks exactly like the ipad pro, i should not have to adjust or tweak anything ST3 should know what device it is running on and adjust this automatically to suit the user, so if i hook up to any device the ratios have already been done and an apropriate setting is automatically applied so there is nothing for the session joiner to do but get on with the show.
The second very frustrating thing is , if i select to join a session i expect to be solidly connected to this session and not drop off so easily, at the moment tap to close knocks you off the session, attempt to go to settings knocks you off the session, it does not make sense why would you want to be so easilly disconnected, this should be rock solid, once you are joined to a host the only way to get released should be by going to settings and unticking the join a session, this makes the whole process solid and reliable at the moment all you need to do is sneeze and you are disconnected.
Cheers Damir
