I get this strange error "On [collection name]: You can only use <, <=, >, >=, !=, and not-in operators on one field per query" on a Firestore Query Action. What does this mean?
In this query I have 3 filters, one with <= operator, one with >= and one with =, and everything is fine. If I try to add a 4th filter , seems like the only operator I can use is =, otherwise I get the error mentioned above. Don't understand what the problem is, or what the error message means...
