I applied the update to version 12 but my splashscreen still says build 11. Not sure if it is related or not but I am working of Beta build 11 (can't update to 14 but that is in another thread).
You need to use the production version, not the beta. I would delete the beta files, just to make sure they don't get used inadvertently and to prevent possible problems with updates. Beta updates don't apply to the production version and production updates don't apply to the beta version.
