Intense lag on iOS - MCPE

I’m getting intense lag during game.

Examples:

• As I’m breaking blocks, they’ll disappear but no sprites, sound or animation will appear for up to 30 seconds after breaking them.  Sometimes they’ll revert to unbroken.
• Traveling to and from the Nether.  The game will stall with my character in the gate not loading to the next area for up to 30 seconds.
• In heavily active areas, I can barely move my character and end up falling or being unable to navigate back to a previous area.

These issues are making it impossible to play the game effectively.  My internet connection is 500+ MBps and up until The Wild update, I was not having any of these issues.
