It's no more glaring than in the early hours of a developing story

The following is an excerpt from The Japan Times of June 22. What does "It's no more glaring than in the early hours of a developing story" mean?

The spread of misinformation ‒ "fake news" if that's more your speed ‒ has long been an issue, but social media has accelerated it significantly. It's no more glaring than in the early hours of a developing story, where facts are scarce but the Twitter timeline moves at a rapid pace.

In this case, glaring means stark, dramatic, obvious, conspicuous with the connotation of being something bad or undesirable.

According to Webster, glaring: obtrusively and often painfully obvious, as in a glaring error

So, what the author is trying to say is that when a story is first developing, there are not many available facts, and the spread of misinformation is most dramatic at that point.
