Pokemon Go‘s Sinnoh Stone is no longer a guaranteed reward in Research Breakthroughs.
The Silph Road Twitter account confirmed that Sinnoh Stones, which let you evolve certain kinds of Pokemon, are now randomly rewarded in Research Breakthroughs like other rewards. They said that it’s possible that there will be other ways to obtain the item in the future.
Sinnoh Stones are no longer a guaranteed reward from every Research Breakthrough, travelers, but are now granted randomly like other awards. We expect additional ways to obtain them in the future, per Niantic’s past statements to TSR, but have not seen any yet. (Hopefully soon!)
It was previously believed that Sinnoh Stones were removed from Research Breakthroughs entirely. Earlier today, user ZenonCrow on The Silph Road Subreddit said that three people in their group were not awarded the Sinnoh Stone when they opened their Research Breakthrough. They even provided screenshots as proof. As more reports came in, the official Twitter account for The Silph Road confirmed that the item wasn’t being awarded at the moment.
Research Breakthroughs are awarded to players after completing seven different Field Research tasks on seven different days. Research Breakthroughs award the player with items, XP and a chance to catch the featured Pokemon of the month. November’s featured Pokemon is Shedinja.

Here’s a list of Pokemon that can currently evolve using the Sinnoh Stone, according to users on The Silph Road Subreddit:
This comes after the end of the in-game event celebrating the launch of Pokemon: Let’s Go, Pikachu/Eevee!. The event included new Field Research tasks, a new Special Research quest, new Raid Bosses, new cosmetic items in the in-game shop and more.
