Program modifications to improve usability based on end-user feedback.

Observed challenges	Actions/strategies to address challenges
Lower computer literacy skills overall	Creating technical assistance tools for various stages of the program. Greater promotion of mobile phone interface and use of app for English speakers
Need for additional guidance to complete the sign-up process independently	Greater promotion of using Omada support staff for assistance. Creating technical assistance tools, that is, video tutorial, handouts with screenshots, and instructions for accessing the sign-up website and completing the account setup process
Need for additional participant communication about each step in the sign-up process	Modifying notification schedule to remind participants more often about where they were in the sign-up process and the expected launch date of the group cohort
Difficulty logging in to the program after signing up	More outreach from the program staff to help participants at the early stage
Desire for more connection with peers in the cohort	Offering a conference call session at the beginning of the program to get group members oriented and connected to one another offline
