Open MobileSheets, tap the three dots at the top right of the library screen and then Sync Library->Sync to another device. Set up one PC as the server (the one that has the changes you want to push to the other one) and the other as the client. Set the sync type to "Update Client" so that changes are pushed from the server to the client device. Also make sure to connect over WiFi. Now tap "Create Server" on the first PC, then on the second PC, tap the entry that shows up and tap Connect. Now the sync will proceed and push over the changes.
