Unable to add apple id because the '10' app id limit in '7' days has been exceeded?

Does anyone have any information regarding this message preventing me from testing apps on the device. Searched s.o. and only a couple of similar questions, all very recent. So I am guessing this to be some sort of hidden 7.3 feature they kindly included with their last release of Xcode? Suggestions that I found on previous answers, would have me creating another apple ID, which I rather not do and although I in principle not against paying to be a developer, I would like to know if this is the official way to get rid of the problem for good. Is there anywhere to find official documentation on the issue, or are we supposed to keep second guessing Apple? Any help appreciated.
