I recently moved countries inside Europe (from € to €) and even though none of the countries involved were on the "you need to make a new account" list, after using the designated form I got a mail that I needed to create a new account to change country anyway. However, they allowed me to keep my old account open for now to ease the process.

So I did, and the first approval took about an hour - I was told to reply to the mail with the details of my new account for speeding up approval - and was subsequently in the "put the ad code and see blank ads until we review your site" step.

Since then I've been unable to log in to my old account, so I'm a bit weary of what's happening here, although the ads from my old account are still showing up (hope my remaining funds - 5 figures - will be transferred or paid in the end)

Anyway, I've been searching online how long the second part of the approval process takes, and apparently AdSense itself says 2-3 days, while there are reports of people having to wait weeks.

Does anyone have experience with this situation and how long the second part of the approval process takes in this case? Since this is a reasonably high-revenue, high-visited site that has been showing Adsense ads for two years now, I hope it would go quickly once I update the ad codes. However, as soon as I update the code, the blank ads mean I'm losing a huge amount of money every hour.

Could I update the code on just some pages of the site, or can I show the blank ads together with ads from the old account, so I'm not losing money? Maybe this will be frowned upon as a violation of policy, even though I'm already kind of violating with their permission by having two accounts for the same site.

Any recommendations on how to speed up the process/lose the least amount of revenue?
