Safari issue - constant logging in of Nest

[circatee]

I am still getting used to MacOS overall, and have decided to try Safari as my default browser, versus Chrome.
However, from Mac, anytime I access my Nest account, I am required to log in.

Any reason why? And, this happens even within minutes of me closing the tab in Safari, and then trying to access Nest again.
Wondering if there are other sites that does this, too, but I simply haven't come across them, yet...

I just reverted to using Google Chrome. One thing I might do is, websites that require a text code (2FA), I may access those sites via Safari.

A shame I wasn’t able to resolve this, and solely use Safari…

I have the same issue. Very annoying.
