Safari can't open Findtime page

Hi when clicking on the "Vote" button or "View your polls" it opens up the outlook mail page but never the Findtime page.

This seems to be a recent behaviour, Sequoia issue ?

Using Safari Version 18.0.1 (20619.1.26.31.7)

https://outlook.office.com/findtime/dashboard

Works fine with Edge.

I have tried both clear the cache and history, no change.

Thank you in advance for the help
