I just saw a upgrade offer in email inbox after 4 hours of receiving it. But to no avail, I couldn’t find it exactly on the website/ app or following the click of button from the email. Worth mentioning is that it also said in the email that the offer lasts for 4 days.

Do any of you have experience with this before? Does it simply expire and vanish so soon or is it a momentary technical glitch?

Cheers and much thanks!
