Did you raise a CSE or did you just simply send them an email?I also got "Update" twice. The first one was mid of Mar which I believe my egibility has been pass and they Updated. The second was on 17th April. 2 days later on 19th April, I wrote email to my visa office to ask why I have seen Updated in my account but there's no change in the profile or any new message, and politely ask them to share any feedback or or status of my application. Few hours later, I got PPR message from CIC account. Hope this will help.
