Hi @Cemre ,
Welcome to Google Cloud Community!
Yes, you are right! The “Database Operations Per Minute” quota of Cloud Firestore is currently at 60 per project by default and adjustable only between 0 and 60. What I recommend is to reach out or file a case to Google Cloud Customer Care for 1:1 technical support as they have the right resources to check your project and tools for the quota increase since you are currently on a paid account.
