Hey @Sylau888, thanks for posting this here.
Can you send me a screenshot of the message you get saying that your Dropbox account is already upgraded?
Besides the email address that’s linked to your Dropbox mobile app, do you have any other emails that could be connected to a different Dropbox account (that has been upgraded instead)?
Let me know, and we’ll have a look.
Hi @Sylau888, could you check for any payments (including both an invoice and receipt) on this page on your account?
As this is related to sensitive billing info, I’d recommend getting in contact with our support team directly to look into this matter in more detail.
You can do this by opening an incognito/private browsing window, while not signed into your account, and accessing this link, choose 'Other' and then put in an email address that you can access, followed by your billing info.
Hey @Sylau888, did you open the link from a private browsing/incognito window?
No worries, @Sylau888!
I just sent you an email, and I'll be happy to see you there, thanks!
