What to include so we can act on it
For tool problems, name your phone model and browser, what you expected, and what happened; audio routing bugs are usually device-specific, and those three facts cut the diagnosis time in half. For content corrections, link the page and quote the sentence you believe is wrong.
For widget and embedding requests, include the site where the widget would live and any sizing constraints. For everything else, plain words are fine.
What gets priority
Safety corrections come first: if any guidance on this site could mislead someone about protecting their phone or their hearing, that jumps every queue. Bug reports on the tools come second, and feature ideas and partnerships after that.
