If the portal is still accessible as in you can access the page after entering your 2FA code, but the application does not exist anymore, it is very likely bad news. However, there is one applicant in the thread that mentioned his/her application was gone but had gotten his/her medical invite after few months, but that is just an exception
Conversely, it is good news (especially after Day 14+) if the application still exists. It probably means they are likely busy on their end, or your processing time is delayed due to manpower constraints, Typhoon/black rain, and will schedule medical for you in due course.
