[Patentpractice] Traps for the Unwary When Filing PCT With 119a-d foreign priority claim?

[Flash]

Sorry if this is the wrong listserv. On my phone with limited selectivity. 

Is anyone else having trouble getting a DAS access code for a Chinese utility application?  
I’m being told that the code isn’t made available until the patent issues, which doesn’t sound right.  It’s coming to me through non-practitioners, which may be the problem of course. I’m not (yet anyway) in touch directly with Chinese patent counsel. 
But finding a work around is proving difficult.  Any suggestions?
