Worker last seen in 6 hours

I’m mining on flypool with 2 z9 mini
It says on both workers last seen 6 hours ago
But they doesn’t appear red and I’m getting unpaid balance added with immature balance to the account

Before sapling it was always refreshing the last seen thing every 10 minutes
My wallet is on Jaxx
