yes I did the same thing and sent an email to SCR about 2 weeks ago but radio silence and I also submitted an IRCC form!I would advise replying to the test email and ask the status of the application. After 3.5 months of waiting, I did the same and the next day, my process was all complete except oath. After 2 days, they scheduled me for oath as well. Not sure if this was a coincidence or the email worked but doesn't hurt to try. I read about similar occurrences in this forum and decided to email them.
