Thought I would make a separate thread in case this helps prevents lost scores at other clubs.
Besides Syncing during the match, there is an option to save a local score log. I've always enabled this when setting up the match on our master tablet. Since this setting was displayed on the match setup screen, I assumed this synced to the scoring devices. Apparently this is not the case and that setting needs to be enabled manually on each scoring device. Once enabled, it appears that it stays enabled when syncing new matches. So you may want to just double check your scoring devices to make sure the local log is enabled.
