When you sign up with a new account: Error: Route "entity.profile.type.user_profile_form" does not exist

Simply installing a vanilla version of Open Social 8.1 with the default modules, when you try to register, after filling the account details (password...), OSocial tries to open the profile form and returns an error:

Symfony\Component\Routing\Exception\RouteNotFoundException: Route "entity.profile.type.user_profile_form" does not exist. in Drupal\Core\Routing\RouteProvider->getRouteByName() (line 208 of core/lib/Drupal/Core/Routing/RouteProvider.php).

I found that the route "entity.profile.type.user_profile_form" was defined before version 1.0-rc2 of the Profile module, after that version they've changed it and OSocial isn't updated. OSocial uses that route on many modules and themes: social_auth_extra, social_profile, social_user and socialblue.

Opensocial 8.1 requires Profile ^1.1 so there must be a reason?
Cheers
