Thanks ISaidGoodDay, yes, they are from IRCC it has the Canada immigration domain and we were asked to submit the documents through Webform.They usually send out approval emails very soon after asking for ADR. Are you sure that the email was from IRCC though? Check DKIM, DMARC and SPF to be sure, they should all be "PASS".
I hope you are right that they get processed soon. What is DKIM, DMARC, SPF?
Thanks.
