Generally Tot's syncing is very reliable. But sometimes iCloud gets confused and you'll see text fail to sync or lose text during the syncing process. Here are a few things you can try to get iCloud back in working order:
 

1) Restart all devices that are using Tot, both on macOS and iOS.
 

2) If that doesn't work, sign out of iCloud on all devices, and then sign back in.
 

We realize this is disruptive, but we haven't been able to find a better way to get things working again.
