What are immature shares

[Squezzi55]

Can someone please explain to me what immature shares means? I am mining with some gtx1660s and few 3060ti to crazypool but I'm see two immature shares and I don't know what they are or why I got them

Better ask the technical support of your pool.
If I understand correctly, these awards will be transferred to your account a little later. Therefore, you cannot control these reward amounts at this time.
This situation occurs with many coins, wait a little if you do not want to communicate with technical support.

Immature shares is just like rejected shares it's nothing to worry about, I got such mining Monero too on minexmr pool, go back and look your miner software you will probably see one or two rejected or stale shares, this don't happen every time
