AD review can vary from application to application. For me, AD changed review after 11 days I think. Anyone who gets ADR, they also get instructions on where/how to upload the documents. Typically, there are two options, 1 - GCkey, 2 - Email to VO. Can choose any option, but I preferred GCkey - the text after upload/submit at GCkeys turn green. For email, the subject line has to be per ADR instruction. For instance, <NAME> <APP> <Number> <VO Code>. VO code so that AD is directed to the officer who requested the ADR.
After submitting either thru GCkey or Email - wait for a days or so and then call the IRCC help desk and ask if the AD is received or not. For me, I uploaded thru GCkey and after calling them to verify, they said they don't see any documents received on their system against the AD. I don't know if it's glitch or some issue on their system, or that AD upload registers after days.. in GCkey account, I can clearly see the documents uploaded, text turn green (submit & sign at last page) and I know I submitted the docs right, I took screenshots on every steps. Anyhow, the agent asked whether I emailed or not, I said as per the instructions, the letter clearly say choose any one option (gckey or email), but not both, so upload on gckey account only. Agent then advised to email, coz apparently they don't see the docs for some reason. So upload the doc via email as well.
So whether you should send gckey or email - choose anyone and then just call them to verify. If they confirm they have the docs for ADR, you then just wait for the next update.
