Whenever I launch a previously-created world I created that does not have the setting for "Multiplayer" switched on, I get a dialog box pop-up that says the following: 

"During online play you may be exposed to chat messages or other types of user-generated content that has not been rated, and may not be suitable for all ages."

If I enter a world that does allow other players to join via LAN, it says the same thing. I have never played on an online server before, and have not experienced this issue until I updated Pocket Edition to the 1.14.60 Hotfix (this morning). If it is NOT an issue and is part of protocol for joining ANY multiplayer world instead of just Online Servers, please forgive me.

However, I would like to reiterate that this issue occured while I was launching a private, pre-created, non-LAN or multiplayer world when this dialog box appeared.
