Invisible bedrock glitch

Works differently for Gamemodes.
Survival: If u walk up to invisible bedrock on survival and exit and then close the game and open it again you well be standing on top/in (I don't know).
Creative: works the same as survival as in creative. but, u can also fly up and go in/on top of it.

This is a really cool glitch but I want to report it anyway.

thanks its is kinda of a minor problem. P.S My first post. :3

I don't know if its on IOS or other it say Xipera Play because that is what I was playing it on when I found this bug
