Please make sure never to sign-in to multiple Cookiebot accounts at the same time in the same browser.
If you sign in to your reseller account and in the same browser sign in to a different account (for example a test account you had before becoming a reseller or the account of one of your customers who has shared the username and password with you for some reason) you risk errors. For example, that domains are transferred from one account to the other or that the accounts are being linked together.
Always use separate browsers if you need to log in to more than one account at a time. Alternatively, make sure that you always fully log out of one account before logging in to the next one.
