It looks like our approach to migrating the ToS prefs in the shared prefs table didn't work as expected, despite tests passing at the time. We should figure out why.

QA found STR for new users and existing users, but we think this bug will affect few users because:

• The new user STR requires opening new windows to bypass the ToU onboarding.
• The existing user STR requires users to have a profile that was created before we required ToU onboarding (138-142) AND for that user to have created multiple profiles at that time, but multi profile support only started rolling out to 0.5% of Release in 140+.
