I haven't received a payout in >5hrs and I have a found block of FLO that has remained unconfirmed for >10 hrs. Is there a problem or will this work itself out in a couple of rounds?
It is not uncommon for a round to be paid up to 4 hours late. Right now it appears that all your work has been paid.
The unconfirmed FLO block is because the blockchain being slow due to bad difficulty adjustment but it doesn't affect your payout at all.
