Can't get the hidden quest

If you attach an image that confirms your clear, you'll get it right away after inquiring 💎 It's a bug that's happening... pretty much everywhere lol Let's go inquire! 🏃

If you touch your icon, you'll go to your profile screen. On the top right of the profile screen, there's a gear ⚙️ icon, tap that. There's a section called Customer Center, tap that. Then tap 'Regarding hidden quests' under inquiry details, and just write what you want to inquire about 😀 It says to write the date in red, but I think just writing the date is fine. Something like 'I completed the hidden quest on ○ Month ○ Day, but it wasn't registered...' is okay 🤗🤗🤗 Let's contact them and get those precious gems 💎💎💎💎💎💎 ♪

Thank you everyone 😊 I got it!
