3/ Other astronomers have looked at the data, and found that it looks more like the detection may not be real. There are problems in the data processing, and possibly in the analysis after. Also, other observations don't show any phosphine.

That's troublesome.
4/ It doesn't mean the original claims are wrong, necessarily. But it does cast some very serious doubt on them. Not just the conclusions, but even if the *detection* of phosphine was real.

It's not clear to me which way to bet here. More data are needed.
5/ It would take 20 more tweets to go into details, so just check my blog (and links to other articles therein). The investigation is ongoing.

Mind you, this is how science works. The team did their best, released their results, and asked others to dig in to the data.
