Same problem.
Revo 2.2.0-pl2
Login 1.7.3-pl (upgraded from 1.7.2)
Also, the lgnupdateprofile.chunk.tpl mentioned in the rtfm does not exist on my install and the lgnupdateprofiletpl chunk was not created.
And lastly, using the plain call
is the only way I've been able to get the updateprofile snippet to work so far.
If I add any properties whatsoever to the call, then the snippet does not work. (does not populate the fields and does not update and reports no error).
