I might be wrong, but I beleive on the basic sub you have a total of 400 hours available to you to be on the labs
Precisely. You get a total of 400 hours of lab time. Every time you start a lab (regardless of the course) the counter keeps increasing based on the number of hours that you spent using it.
The problem is I don't have the current running lab and I just started using RHLS only 3 or 4 days ago. Now my lab time becomes 74 hrs already but I haven't run any lab yet for today.
I am having a similar issue my lab reports 612/400 hours while i might have used it only since the subscription for 5-8 at most. I have opened a case. as my experince and my colleagues that the email they usually drop and no responses.
