Just a query !!Hello Dear
It is really a positive sign in your application. As your application was picked up by a visa officer and now from my point of view it’s about to finalize. As per my experience now when they will start issuing DM and PPR you could be just one of them(the same thing happened in 2018) as well.
Good Luck
They will start issuing PPRs here means they will sent PPRs in bulk???
You also mentioned about last year's trend just wanna know that do they usually send batches of PPRs???
