@geonz When working through the archive I limited myself to 2 or 3 per day. Now that I've caught up it's one a day. I'd recommend doing a few past ones to get the hang of it, then just going with the daily puzzle.
You can always ask for a hint, though it breaks your streak, and that's why doing past ones for practice can help.
A chemist found that a particular reaction took 1n hour and 20 minutes when they were wearing a particular sweater, but 80 minutes when they weren't ... how is that possible?
"WhatsApp messages are end-to-end encrypted, but user data is not only about messages. That also includes the metadata such as user location, which contacts the user is communicating with, the patterns of when the user is online, etc. This metadata according to your privacy policy is indeed used for targeted ads across Meta services."
What's the alternative? I use Signal, and it's nice to see it recommended in the Forbes article.
"But for those worried by user tracking—even from metadata, or those who simply want to use the most private, secure and cleanest platforms, then there’s always a case to switch WhatsApp for Signal."
And, well, the wording was, in part, intended to prevent people from thinking the matter was fully settled without giving away too much about what is settled, and what exactly might still be unresolved.
