Don't rely on the online system its often times imprecise. The written notices is what you should focus on. Call the customer service number if you don't hear anything in 90 days. Removal of conditional green card can take up to 1 year.
The best way to get updated information on your case is to call USCIS directly because the actual RFE might not appear on the online status.

I never rely on the online database as that requires human input. If your case has been pending too long (more than the posted processing times) contact CIS and ascertain why it is taking so long. If you're not satisfied, hire a lawyer.
The online case status system is not a "live" system. Information from various live systems are "dumped" into it every day or so. Unfortunately, it is riddled with errors and just because it says something has happened does not mean that it is true. For example, just because it says a case has been approved does not mean that it has. Likewise, when it says an RFE has been issued does not mean that it really has. A lot of times logic and experience got into telling whether the information is reliable or not.
