I often use MSPro on two or more tablets, that are connected as server/client. When I select a song on the server tablet, the clients follows.

Occasionally, while processing a setlist, a client can get out of sync. For example, when the client player accidentally touches the screen and moves the scroll. It then stays out of sync.

Would it be possible to re-sync client(s) with the server at the start of each new song from the playlist? Or have some kind of 'restricted client' mode where all user input from the client is ignored?

Yes, at the moment the client/follower can override "being on the same page".
At the moment the leader should watch followers not to touch the devices while loading pieces. Easy to do in smaller ensembles.
If followers do touch at the wrong time leader needs to repeat the action to sync again.
I learned these lessons many times and will now always watch followers while I am selecting a new piece/song as a leader.

On the other hand I don't want to disable the followers to not to perform any action on their devices.
