Quick reminder that if you are after Raikou and not Snorlax as your research breakthrough reward, do NOT collect it until 1 PM PDT tomorrow (25 hours and change from this post - see https://p337.info/pokemongo/ for a live timer and the time converted to your local time). If you trigger your breakthrough any time before that, even if it is already August in your time zone, it will still be Snorlax.
