IG Email keeps reverting

I am doing basic F/UF and posting on a client's account right now with Jarvee and keep running into issues with the account locking me out and hitting email verification every couple of days. I've changed the email AND phone number numerous times to one that I have access to, but EVERY TIME the account locks me out it reverts to the client's email (which his instagram was originally created with). Extremely annoying because I have to ask him for the verification code, and this has happened about 6 times now.

I'm using very mild settings on Jarvee, posting original content daily, with no proxies or VPS as this is my first Instagram client and I'm only running this and one other IG account on Jarvee.

Any Jarvee experts out there that can help me figure out this issue? I'm desperate at this point.

Yes, you might want to reset the ID of account within Jarvee, verify it again and it should be fine. If it reverts back, you may want to tell your client to sign out for a few days and also keep only a phone number in account and erase de email.
