Same situation here. I actually had my first sub account created, was mining to it on Friday (wasn't sure if I was actually mining or not).
Saturday came and after flip flopping between Antpool and UUPool I went back to Antpool. My original sub account was no longer listed! So now I thought I wasted mining time to a now non existent sub account. So I created a second sub account and started mining with that on Saturday.
Sunday rolls around and I have balance in my second account (as expected and it actually shows a balance) and all of a sudden my original sub account is listed and it has a balance (from the Friday mining)!
To your point - I have not had that original mining amount paid yet out of my first sub account from Friday.
To be continued I'm sure...
Yep. I did get a reply from Bitmain Customer service about lack of payment that they "are working on it and to be patient". At least they're responding, I guess...also have my BTM in "Paying" status all night, same as others. I must've done the same as you as I have a bunch of sub-accounts cluttering up the Antpool GUI, but the one dashboard that shows the balance has an address in the "settings" page to hopefully all is ok.
I just love how you can delete sub-accounts and workers, and they don't even go away or if they do and you try to add one back it says it "already exists!". What a crap website...Good luck!
