You need 2 accounts to test the app.
1st one is: firstname.lastname@example.org (password: testaccount )
2nd one is: email@example.com (password: testaccount)
Once you log in as firstname.lastname@example.org you have 2 sample types of predefined messages that can be sent to email@example.com.
Touch the message in order to send it.
Mark - customer - It is the message to Mark about his customer arrival. Once you touch the message on firstname.lastname@example.org, the message is deleted and the confirmation is sent back to email@example.com.
Under "cleaning needed" button there are 2 exactly the same behaving messages - about a need to clean room1/room2. firstname.lastname@example.org can reply with ok or done status. The ok/done status is later presented on email@example.com. The done status also deletes the message from firstname.lastname@example.org account.
All incoming messages can be deleted by touching them.
All messages are predefined by a customer with my help outside of the application. Then are reused in the application
