Restoring backups does NOT work. This is the second time now that my MX Master 3 customizations have been COMPLETELY wiped. Restoring backup only presents an option for a backup that was created "a few seconds ago" which is absolutely useless when a few seconds ago the customizations were already wiped. There is no way to select which backup to restore to, for example yesterday when my customizations still existed. No, I did not just set up a NEW device, I just restarted my computer. This is ridiculous if I have to reconfigure my mouse for 10+ applications every time this happens.
