Mac Book Pro Touch Bar keeps flashing
My Mackbook Pro 2018 touch bar keeps flashing. Every time after idle (20sec) when not using the keyboard on the top right corner appears a bright flashy rectangle. I have read forums and it seems to be a hardware issue. Just went to an Apple support in Ireland, Dublin and they said the keyboard, touch bar, and battery need to be replaced and costs around 700€, this is ridiculous and they said Apple won't pay for it.
I have heard it's a common problem with this model. Any experience or help with this one?
Thanks in advance!
MacBook Pro 13″, macOS 11.5
