Hi @Bryanna,I don't think this is the reason for the delay.
Just for peace of mind: You can send an email to CPC-O to inform them about this
I did emailed to CPC-O about my education details mistake but no reply from them. Also no reply, no status change on my application. Is there something where I can get real time scenario about what's going on my application for so long? My status just shows, 'We are reviewing whether you meet the eligibility requirements' from the day I submitted my application i.e 03rd October, 2018. Nothing changed till yet. I think so they haven't even touched my application.
