U-throw, rest fast fallers, questions

[CanISmash]

im having problems and I have no idea why. I get up-thrown and the moment I'm grabbed im always holding left or right but after the throw it seems i consistently am not di-ing.... or easily put in a position to rest. I thought this was fairly easy to escape.... tips or any idea what i may be doing wrong?

Never stop holding a direction.

You need to be holding either left or right at the time you're being thrown, not after
