A summary...
The authors refused to allow the withdrawal of the Exercise review, despite David Tovey's (previous Editor in Chief) request that they do so. In October 2019 Cochrane published the amended version which still says there is moderate evidence that Exercise is effective for people with ME/CFS. At the same time they announced they were going to update the review because the methods were outdated, the population included people without ME/CFS.

"I can confirm that work will begin on this new review at the beginning of 2020 and that we will keep patient groups regularly informed of progress during the subsequent months.”
In Feb 2020 they announced Hilda Bastian would lead an independent advisory group to help with the new review

The advisory group idea is a "pilot" for involving patients and the public in "high profile" reviews.

"The complete updating process for the review is expected to take about two years from early 2020"
The FAQs page has not been updated for over a year, although I know that many questions have been asked frequently on Twitter and by email, mainly along the lines of "what's happening?"
In the meantime, although there was some delay, progress was made on the NICE guidelines which. Unless NICE decide between now and 21 April to promote the grading of the evidence from "low" and "very low" to "moderate", the guidelines will contradict the findings of both Cochrane reviews.
If newly diagnosed ME patient does some research and then goes to their doctor waving the 2019 Cochrane review, they could demand to be prescribed graded exercise, which could harm them. Same with the CBT review which is even more enthusiastic about CBT as an evidence-based way to recover from ME/CFS. Is the doctor really going to argue with a patient with a Cochrane review in their hand, unless they are aware of all the kerfuffle, and know the NICE guidelines have changed?
People are encouraged to read plain language summaries of Cochrane reviews where caveats about outdated methods, or omission of more recent studies are not displayed. Many people in the world only have access to the summary of Cochrane reviews, and nothing else. It is usually only the summary that will be translated into other languages. Many countries use Cochrane reviews wholesale to inform their national clinical guidelines. Many people live in countries where there are no national clinical guidelines.
