We are also in the same boat and there is no update!!! I think we have to be patient and that's what we can do at this juncture. On a lighter note many people from Jan and Feb got their PPR....
I have no idea about the procedure either!!! Many people from Jan and Feb 2018 have got their PPR and some unlucky one are waiting patiently.... I will keep you posted in case scenario changes or I hear anything :)
