Since the agent already mentioned that it is still under normal processing, you shouldn't worry. There could so many reasons for the delay as it varies from case to case. Don't stress over it too much.I had visa refusals that might have triggered REVIEW REQUIRED in my application...... i called and the agent said my application is still under normal processing (AOR JULY 15).
Does that mean 6 months for PNP/EE applies or REVIEW REQUIRED pushes the file and normal processing times does not apply anymore ?
