Tell us what is wrong
The Log is in beta and there will be mistakes — misheard names, a speaker attributed to the wrong person, a roving report filed under the wrong parkrun. Every one you report gets fixed at the source, so it stays fixed.
What is most useful. Wrong or missing names in a transcript, a speaker labelled as the wrong person, anything that reads as nonsense, and anything that is hard to use with a screen reader or on a phone. Automatic transcripts are unchecked by design — those are expected to be rough, so no need to report them as a whole.
