Flits has updated the wallets of Sapphire (SAPP) to the latest version (126.96.36.199).
This version is a protocol update and therefore requires a restart of your SAPP masternode(s).
How to restart my masternode?
1. Go to your Sapphire (SAPP) wallet
2. Find the "Masternodes" tab
3. Under the "Ready to start" section you find the nodes in need of a restart
4. Press a masternode, and then in the pop up window click the blue "Start" button
If you have trouble starting your masternode(s) again, please open a ticket in the in-app support.
