Update:No, I have not received pre-arrival services. Nothing on ECAS has changed since PPR.
I received an email from the High Commission in Kingston and they confirmed that they received my husband's passport and courier envelope and it is currently in queue to be processed. They mentioned that if they require any further information to further process his application, they will send a message in ECAS. I checked ECAS and there are no updated messages as of yet, and it still does not show that his passport and envelope were received.
