We are on a range of Mongodb clusters, starting from M20 up to M60. While the concept of auto-indexing is appealing, it is disappointing that this feature is not available on higher tier plans. When a customer upgrades from M30 to M40, they lose access to this feature and are forced to manually add it, which can be burdensome for them. Therefore, we kindly request that you investigate this issue and provide a prompt solution.
