Yes it is completely normal to not see any updates on ECAS. Mine went from application received to decision made /medical results received over night, it never changed to in progress. This was the case for a lot of Paris applicants, just recently we have noticed that people are starting to see ECAS change to in progress (but not everyone so don't stress). So you may or may not see updates online, I guess it depends on what officer it working on your file.
If you provided them with an e-mail address they will e-mail you ONLY if they require additional information from you. If they do not then if/when your application is approved they will mail you your COPR by regular mail.
