I have a development environment with two shards, one configuration server and one router as illustrated below. I have a sharded database "mydb2" and a sharded colleciton "mycollection2". When I insert data to mycollection2 from router, it is inserting to s1. And next time s2. And s1 again and so on. How can I insert data to both two shards same time. I am using MongoDb 4.2.3
UPDATE: I added s1 and s2 to the same zone. I declared a shard key range. But nothing changed. I insert data to the collection with ranged shard key, bu data is not distributed.
