Hi there,
Thank you for reaching out to us.
I tried our
sample Ad Unit ID on the
sample app and I wasn't able to reproduce the behavior on my end. It seems that this is a creative specific issue as you mentioned that some of the full screen interstitial ad's close button is way up in the corner.
That said, I would recommend contacting out
Product Support team as they are more equipped on handling creative issues.
Regards,
