To ensure scalability, performance, and high availability, Mendix has implemented a stateless runtime. Hence putting the messages into the same Microflow will get the behaviour you describe. Depending on your use case, you could consider using a page to display the first message you want to show at the end of the microflow. You implement a second microflow under the “OK” button showing the second message on the second page (or message if it is the end). Please think about how to give the information from the first microflow to the second microflow via Entities/Attributes. Don’t forget to clean up the data in the Entity/Microflow used for information sharing if it should not stay there forever.
