Did anyone’s ETH staking rewards just randomly drop?

This week I noticed my crypto exchanges staking estimates dropped a huge amount and their support is not explaining why. I tried to see any news or announcements regarding staking rewards (globally and on exchange) changing but nothing. I know the amount can fluctuate but I've been consistently getting the same/similar amount down to .000001 increments due to compounding. Now I'm getting .001 less eth this week. Can anyone relate? TIA
