I don’t quite understand why there is “Ihr” here…it looks like the informal plural you, but then it doesn’t agree with the ending on “werden”, which suggests the formal you.
You are right, the sentence is not correct.
It should be 'Ihr werdet verschont bleiben" or 'Sie werden verschont bleiben." Otherwise it’s not consistent.
They’ve updated the text but not the audio.
The audio still needs to be updated.
