I haven’t used zksync: so be suspicious of my comments 
. But from what I understand only Era is now supported (“future payouts will no longer respect zkSync Lite preferences. Future payouts will simply choose your preference between zkSync Era and Layer 1”).
So now that we’re in August… if you hadn’t switched to “zksync-era” by the end of July the system will try to pay your L1 address: and L1 has higher minimum-payout amounts. You may unfortunately be in a position where your first-3-months-75%-holdback combines with that high L1 minimum… and you still don’t have enough banked to receive a payout in August either.
If so, that would suck, but it does get better. Your payouts increase as your node grows, and the holdback percentages drop: so you soon start reliably receiving coins at the start of each month. Hang in there!
