No activation link from test instance


I wanted to try gitea out before making a VM with my own copy. I created an account and waited for the activation link. Clicked to send it again after a few hours, and again, but the email never came. Tried a different email (gmail account) but with the same result - no activation link, not even in spam. When creating an account to post on this forum I provided the same email as during the first registration and the email arrived (to spam, but I got it).

Am I doing something wrong? Couldn’t find any instructions how to work with the test instance…

Thank you in advance for your help
