I just noticed that when checking for a new version in TV11, it prompts to install Beta 12. In the past, updates to new major versions would usually show two buttons: update to the current version (i.e., 11.xxx to 11.yyyy) or the new major version (i.e., 12.xxx).
I had a user who did the update the Beta 12 without realizing it and I need to keep our machines on 11 for now.
