Dropping collection did not work on sharded M30 Cluster in Atlas

Problem Statement/Rationale

I tried to drop a sharded collection in an Atlas M30 cluster with 4 shards and got:

Atlas [mongos] hsk> db.load.drop()
MongoServerError: timed out waiting for hsk.load

Steps to Reproduce

Create a multiple GB sharded collection and try to drop it.

Expected Results

MongoDB Enterprise mongos> show collections
load
MongoDB Enterprise mongos> db.load.drop()
true

Actual Results

The timeout error happens.

Additional Notes

I can provide the load script and re-run the test if needed.
