Link address issue

Hello everyone, I have noticed today that the structure of the link has changed in the different accounts that I manage.
For example, until Friday the structure was: https://zoom.us/j/98121xxxxx and today the structure is: https://us06web.zoom.us/j/98121xxxxx
Is this some own mistake? or has something changed? It has even changed in the meetings that had already been created before..

Thank you very much, I await your comments.
