Keep logging into wrong account

I got two openstreetmap accounts, signing up with two different gmail. When I tried to log into umap via the second openstreetmap account, the redirected page keeps logging into the first account and loading the map owned by the first account. Even if I use another computer with incognito window and different browser, the same issue happens.

Attached files show the issue, HKMarineLife is the second account that I want to log in to Umap via openstreetmap, Anna9797 is the first account that the page automatically redirected to.

Any idea on how to fix it? Many thanks!
