Testers couldn't find mailbox pairing screen
All participants successfully installed and created accounts. On the other hand, linking devices was one of the most difficult tasks for all participants.
The common pattern for all was to misinterpret the device-linking process as adding a new contact. The first instinct for four out of five participants was to click on the + icon and try to “add a contact nearby”, they chose that because the devices are near to each other.
The second place they went to look for the feature was always the sidebar menu. First, they looked at the options there and the connection icons. They guessed that linking devices is a form of connection, so they would find it there. One of the participants assumed that the “Internet” icon represents the Mailbox connection.
On the third attempt, they could all find the Mailbox option, listed under the Settings menu.
