[GB] Revolut - Interest earned on US savings account for Ultra Plan

I have a large sum of money ready to be transferred from the US to Revolut, but the % AER they offer under the Ultra Plan is not visible on the website at all. I have Metal now and see 2.75% AER in the app, but before upgrading, I would like to know how they remunerate under Ultra. Is there anyone in Ultra in the UK who would be so kind as to share this with me?

I have a friend in Portugal who confirmed they see 3.68% AER in USD.

Thank you
