1. How will a user be notified of the update?
2. Is it possible for them to bypass it, ignore it, or otherwise state they did not see it?
3. Is there anything else we should be aware of regarding this before we go ahead?
Thanks for raising this question around terms of service updates. If you force all users to view the update, this will be presented the next time the user accesses the site. There is no known way to bypass the update, so this should ensure all users see the update and agree to it.
Let me know if you had any other questions.
