My worker is still showed in the stats page with the current hashrate, but in the Workers - workers tab and at the top right near my username it shows 0GHs or ?GHs. Is that normal Kano?
The pool generated stats take a while to change. That can take hours to match your miner.
Though, if you don't wait at least a minute before you started mining, your top right numbers may well show as zero.
The KanoDB stats lines for your workers are immediate values, but not accurate in measuring your hash rate vs your miner.
They're there so you can see immediately what's happening when you first connect a miner.
