I trained it all the way up, aiming for the Dynamax Raid, but...

I put so much effort into strengthening Cinderace, but I forgot to check the date and missed it 😭 Also, during the starter Pokemon appearance rate up, I couldn't get a good IV Fuecoco and just ended up hoarding candies 🍬 When will the next Dynamax Raid be? I'd like the starters to appear, but it might be too frequent event-wise 🤔
