Answering a couple of your questions. Yes your app can be in China, they send apps to other VO's when the LVO is very busy so apps can be processed faster. That is a good thing for you, means your app is being worked on or will be soon.Application received shows after in process or before?? after the application received it will shows the DM?
The NORMAL sequence of events is, after your app is received at the VO ECAS should show RECEIVED, then once the VO starts to process it ECAS should change to IN PROCESS. After it has been processed and a decision on your app has been made then it should change to DM. After that, assuming your application has been approved you will receive PPR. That can be a few days to a couple of months.
That is the normal sequence, right now with covid, updates are not always being done in the normal manner. Relax, all is good.
