What problem do you consider to be the worst one regarding documentation in software projects?

Hi! Taking into consideration your whole carrier as a software developer, what problem do you consider to be the main pain point about documentation in companies?
I have created this short survey where developers have to rank problems about documentation that they consider the most important ones. Your feedback is much appreciated and maybe we can solve some of them together! https://app.opinionx.co/8b5d90b5-d724-4464-9abe-f6c4ecbd2ebb
