I sent in a support ticket for this already but wanted to make the community aware in case it comes up. I had a rare scent capsule basically not work for me for about 12 minutes (so that’s 7 opportunities for spawns). I figured I had nothing to lose so i restarted the game and suddenly I got a spawn off of the scent capsule. From that moment forward my capsule worked normally with spawns every 2:00 minutes.
You should always get a spawn on the Rare and Epic capsule immediately, and then every 2 minutes (so 18:00 remaining is spawn number 2). If you happen to have this issue, I’d recommend force-closing and restarting the app for the time being. I’m sure it’ll get fixed as Ludia is pretty dang great at addressing issues, but I’m thinking nothing will be done for my own missed spawns and wanted to make sure others know to try a restart to hopefully not lose any spawns.
