Multiple Users in same room

Our household zwifters have now increased to two

one with tacx neo, ipad and companion on iphone
one with tacx neo, macbook pro and companion on iphone

Today, we both wanted to do the uphill battle event and once the event started, I was still showing at the startline on my ipad but companion had me as participating, which I complete 26 stars. However, there is no record of me having done the event. Also 15 mins after the even finished it still showed me as zwifting in the activities of the companion app when I wasn’t.

Are there restrictions when multiple users want to zwift with their own equipment and logins in close proximity?
