I know this must be upsetting to you, but if you had 200 approved from the old account, I would think that these rejections are just a glitch on their end.I did around 200 of the $0.60 ones for Alexandria and all were approved with no problem. They're exactly the same as the current ones except they paid more, and were from the Alexandria account. I don't know what's going on, honestly. I think the new account might be managed by someone different on the Alexandria team. It seems that Alexandria isn't just one person, because I noticed from past emails with them that more than 1 person emailed me back when I sent them an email.
Hopefully they can get this sorted out.
