You are using an old version of Internet Explorer. Why?
Polaris doesn't work in old browsers, and neither should you. Upgrade to the latest MS Edge, or better yet download a better browser such as Chrome or Firefox.
Polaris is going down for maintenance on Monday the 15th December 2025
from 5:00am
till 9:00am UTC
This means that you will not be able to use Polaris during that time.
