Problem: Salon clients who want to change their email address need to contact the salon, the salon contacts us and then we update it, and communicate it back to the salon's client, sometimes via the salon. This is very heavy touch and not an edge case - it might surprise you that it is the number one support ticket driver in Finland. It's people changing work address, student address, old email providers to gmail, and married women who have changed their name. If a salon changes it in Phorest Cloud, it won't change their online booking account email address. We don't see the clients who don't want to contact the salon so they sign up again with a new email address, and a fake phone number, creating a duplicate client.
