i FINALLY SUBMITTED MY MASTER STREAM APPLICATION
Some experience and advice:
The last time I logged in, I also saw the duplicate attempts I made before. Still the system was not stable. At some points it still showed no documents were uploaded when I clicked "check error" and if I tried to upload it still showed java blah blah blah. But as long as you are sure you've uploaded your documents, just keep refreshing. Eventually it will show your application is valid.Then you make the payment, the documents were still there when I went back and check after submitted.
Just one question though. for the "residency in Ontario" form part, I did include all the Ontario addresses I lived in but they never showed on summary part. When I went back and checked they were there. But they just didn't show in summary. Anyone has similar experience?
