Sorry to double post but my previous post was shortlived, as I have been able to verify via the different email, so far so good.
Sorry about that and thank you for your help, I edited my post in case anyone comes across it
In such a case, you should edit your other post and not write a new post.
But basically it is of course very good that you have now received the mail and hopefully there will be no more problems and that you can now carry out the verification properly.
However, it would still be interesting to know why you had to change your email address. Perhaps the support team can give you more information here?
