is the 46mm braided solo loop band working with Ultra 2 and 3?

I recently traded my Ultra 2 for the Ultra 3. I have used the 46mm braided solo loop bands with my Ultra 2 in the past, the sales rep told me they would no longer work on the Ultra 3, because they slide through and not stop where that small magnet is.

I was able to attach my old solo loop band to the new Ultra 3, but the team member kept saying that can't be true.

I am now hesitating to order another solo loop band, although my old band fits just fine.
