Hello,

Michael here from Mobile Ads SDK support team. Thank you for reaching out to us.

As per checking to your shared information, it appears that your concern is flutter specific issue. Thus, we would recommend to post your concern instead to flutter plugin issue tracker via this link.

As a side note, I have removed your first message on this thread from forum since it contains private information.

Regards,

Michael Angelo
